This is the excellent manual, but author forgot to attach stirrer connector to avoid vapors releasing through stirrer neck.

It can be worked up from decarboxylation of Proline. There's documented information out there; however I'm not sure if there is a thread on this forum though. Maybe that'll be one of my first contributions as I've now made it on three occasions.
Hi.thanku for your post.sorry i do not have a well educated answer for you.i too will be attempting to carry out this synthesis as well.ive be cramming the chemistry and general chemistry behind it for months,while collecting the things needed.from a near idiots standpoint(me),if the crystals disappeared they where solublized by the solvent,the acetone.per video,a-pvp is said to be partially soluble in cold acetone.acetone is generally not very water containing ive seen.as a idiot,lol,i question where the crystals a-pvp? And was the solvent dry enough? Hope im understanding u correctly.i will follow you.best wishes.amazing video! Respect to its creators! in this regard, I have a question for the respected community, the fact is that I exactly followed the instructions from it, and at the very end, when I brought pH = 6, and put the vessel in the freezer, after almost 2 days I took it out and I saw that almost nothing had formed in it, except for a handful of crystals, which, when washed with dehydrated acetone, disappeared without a trace. what's the matter? what exactly did I do wrong?
the ph value must be 5 not 6 6 is wrongHi.thanku for your post.sorry i do not have a well educated answer for you.i too will be attempting to carry out this synthesis as well.ive be cramming the chemistry and general chemistry behind it for months,while collecting the things needed.from a near idiots standpoint(me),if the crystals disappeared they where solublized by the solvent,the acetone.per video,a-pvp is said to be partially soluble in cold acetone.acetone is generally not very water containing ive seen.as a idiot,lol,i question where the crystals a-pvp?

don't leave it in the fridge for 2 days, just leave it for 12 hours
Sure sounds like your solvents weren't anhydrous. If you saved them you can recover the alkaloids
Further to this, I thought, may be my HCl was not 37% as the bottle cork was open when I found it, so the strength of acid would have been depleted. That might be the reason to use more volume of acid to reach at pH of 5 and hence more water was introduced which stopped the pvp.HCl to crystalize. Therefore I added sufficient QTY of dry acetone to lower the percentage of water in the solution. However, after putting the solution for further 16 hrs in freezer, I found no crystals but saw a thin yellow layer of unknown liquid, floating on acetone surface. I am surprised what is this. It can not the watery solution of pvp salt, as water is not only heavy than acetone and Et. acetate but also miscible with acetone. It can not be pvp free base as the pH is still near 5. Moreover, for the sake of argument, if it would be free base, it would had been dissolved in organic solvent i.e. mixture of acetone and Et.acetate. Can any friend suggest what the hell is this which is lighter than acetone, non miscible with organic solvents, neither it is water nor free base.....I m unable to understand, kindly share your valued opinion for my guidance. thanks to all.Hi to all gentlemen. while working for pvp.HCl synthesis, bromination was successful. However, during amination, color of rxn was faded and never turned back deeper after complete mixing of pyrrolidine. During crystallization, pH was made 5, but the very little crystals came out after resting for 16 hrs in deep freezer. 10 ml of valerophenone and other chemicals in proper ratio gave only 0.8 g of PVP.HCl dry crystals. Can any one identify the reason for such small product, while every step was exactly same as advised.
Vapors are ALWAYS something you want to avoid inhaling when working, hence why a fume hood is good to have. If not then use a well ventilated area or be creative. Safety firstHello, does someone know if in this synthesis, the alpha-pvp vapors can be a problem ? Is a fume hood necessary ?
Your information is amazing.Did you guys know what valeraphenone comes from valeric acid ( of course you did) BUT DID YOU KNOW THAT VALERIC ACID COMED FROM THE PLANT VALERIAN? Valeria officianalis It's an invasive species in the United States and is common in Europe and Asia. People sell it dried in bulk on the internet.
It's less obvious if you call it pYour information is amazing.
I found valerufonone on one of the sites, but it is risky to buy it, because I think everyone knows that valerufenone is only for alpha.
What do you think ?

It has also been used in the synthesis of various heterocyclic compounds, such as pyridines, pyrimidines, and thiophenes. Additionally, 2-bromo-1-phenyl-pentan-1-one is used in the synthesis of polymers, such as polyacrylonitrile, polyvinyl chloride, and polyethylene
I tried to buy from this guy and he laughed at me insulted me and said he was going back to bed. In China, turds sell precursors, but they actually don't. Made me tell him the CASI
Suppliers from China
I believe it is exactly the same procedure using methylene-dioxy pyrovelarophenone < a-bromo-methylenedioxy-pyrovelaraophenone<MDPV< MDPV hclI'd love to get syth for MDPV, is it muchore complicated that a-pvp? Also how necessary is the recrystallization processes? Wouldn't the HCl be more suitable for IV use?

Not true.These people sell pretty much everything under the sun. They're basically the Amazon of China. So you can expect them to know everything about every item.
@NinjaFlakkaZombie Well because Chinese vendors advertise it at prices so low that it's impossible to look away. They no longer offer it for sale in the open forum but if you pm them, they offered it to me for about $125/kg (2-bromo-4-methyl-1-phenylpentan-1-one) and $115/L for the pyrovelarophenone equivalent. I wouldn't accept anything illegal from China. The risk is astronomical in my opinion. I have bought it off of a major online marketplace, received it, sent from inside the USA, with no fanfare, no questions were asked and it's been 2 months and is long gone from my possession. It was expensive compared to Chinese prices. Basically $4/g.
The person is either licensed to receive such things ( the DEA does issue paperwork for businesses to have things of the nature), in a position to procure them with little risk ( such as the faculty of a University department licensed to possess it)or has put a lot of effert into obscuring his identity through incorporations business licensing and mail forwarding
this is very true but having a cheap uncut substance is whole different world from street grade. one that i did not discover untill chem came in my life but its been a life time devotion tho and a huge invesment . i sleep well at night knowing what serve is free from toxic cuts and fillers and one less persson that gonna die from fent Jesus man, you had me scared for a second, then I realized that you are just a tad dramatic. To be fair the police and government in general are a bit dramatic. So you're with the government you say? I know there's enough hoops to jump through and walls to hide behind that a person could have a package intercepted and evade identification, but the amount of effort it takes is more than the amount of effort it takes to synth 4-mmc starting from valerian roots or mdma from Sassafras bark. None of these things am I capable of not do I think I can learn them in the amount of life I have left. I would much rather just buy drugs but the quality is so low where I'm at that one can hardly extract or purify it to a usable level. It doesn't even matter if you buy expensive or cheap drugs, they're all neutered.
Most of that I Can't understand but the government thing was a joke of course and yes it's hard to remove adulterants sometimes impossible and an uphill battle because you usually don't know what they are. I pay top dollar for drugs but even then I rarely get high purity. A couple years ago I reliably got cocaine that titrated to 78% for $350/3.5g. it was the best stuff around, every one agreed. I paid the same price for the same amount of what was supposed to be crystal mdma a few months ago and I go purple crushed powder. It tested positive on 2 tests but it took 600 mg to get high onHaha yeah totally with the government. I spent a year doing surveilance of a prison cell well.a couple months to honest
Tho actually it's nor.dumb to think this way, the cops come after clients too depending on products bought and location (let's.fscw it sereot7ped.dxist for a reason Anand yea police are very terrified of riding in cars or doing too.much nkn work.work.
It's best not go trust.anyonr here
He'll even.heisenberh could br a cop... it's unlikely but.as an example it's just u never know so I get.pissef o
Well I took 300 and an hour later another 300. There's a mountain of purple pressies going around right now that people are warning about being so strong, and I think the guy probably just crushed those up and sold them. I'm thinking 6 pressies=3600 mg and has an actual 1800mg of MD in it. You know bk-mdma becomes regular mdma in 1 reaction. I want to say a Wilkinson, but I didn't look it upwhere i am from you 350 for a cut and your lucky if its 10percent (good stuff) is lucky to break 20 its very bad.I have seen that purple powder making the rounds i wonder if the there a small amount of mdma in with a analog i have seen many snyths from sas to pmk and never did i see some out purple like that maybe shades of purple but good mdma should be a stunning sparkly crystal and never take 600mg i rateher bk-md at that point
This is not true?! Do you know HOW many times I was asking for 2-bromo-4-methyl-1-phenylpentan-1-one AND NOBODY had it.
? What risk do you have if you don't order something on your real name and address?I wouldn't accept anything illegal from China. The risk is astronomical in my opinion.
I'll screenshot the convos if you insist, I've gotten 5 quotes for both. I can't show you Precursor-supplier's because he has auto self destruct on his telegraph.This is not true?! Do you know HOW many times I was asking for 2-bromo-4-methyl-1-phenylpentan-1-one AND NOBODY had it.
No, only everyone wanted to sell all kind of other chemicals with 25kg MOQ.
