Shake and bake method for 4mmc

[Netflix]

Chemicals
{100g}
2-bromo-4methylopropiophenone
{500ml} dcm toulen or benzen
{200ml} methyloamine 40% in water
{3x300ml} cheap water from shop with no gas!!!
{500ml} acetone technical from the construction shop
{55ml} acid hcl 35%-38% if you have 31% acid then we need more to use
This all what we need to made this way

NetflixU said "cheap water from shop" but u dont need to use distillate water? Demineralized water can be good?

ymaaahDrinking water is usually reverse osmosis and UV decontaminated.

StarWarsI worked a lot with alpha halogenated ketones in University lab and lachrimatory effect was always a problem... I know why it is worth it because I am also well aquainted with the mephedrone high so thumbs up!

HerrHaberThere need also wash water with soda and later 3x water and extraction with dcm and later need use magnesium solfate and last step with acetone and acid

StarWarsI have a question, why he takes the top part of the solution to heat it? the bottom part is 4mmc freebase so why he takes the top part?

ymaaahHi. 200 ml 9% 2-bromo-4methylopropiophenone mean that i need 182ml of water mixed with 18 gram of 2-bromo-4methylopropiophenone or different weight and i have to use other solvent ?
How you sorting out metylamine and HCl in one pot method?

whats the yield? Not a lot I imagine..?

Looks cool, might try it out one day.

Somebody know if this reaction come with methylamine 33 % in methanol

breathing.fireNo only with metyloamine with water

Ok, did I understand this correctly?

Step 1: Two solutions are prepared:
Solution 1: 100 g of 2b4m are dissolved in 500 mL of DCM
Solution 2: 200 mL of a 40% methylamine solution

Both solutions are combined in a container, which is then sealed and shaken for 30 minutes.

Step 2: Approximately 200 mL of water is added to the mixture and shaken.
The aqueous phase is discarded. This step is repeated 2-3 times.
The lower phase now consists of DCM and 4-mmc freebase.

Step 3: A solution is prepared consisting of 55 mL of HCL and 500 mL of acetone.
This solution is added to the dcm/4-mmc mixture until the pH level reaches 5.5-6.0.

Step 4: The solution is evaporated until the 4-mmc precipitates out as a salt.

RegulierTierthe hydrochloride should precipitate upon acidification, and partial evaporation is inevitable but I'm not 100% sure you should waste your time trying to evaporate (rather concentrate) the suspension, instead place it in the freezer for some hours and then filter it, you are advised to let the filtrate (remaining liquid) evaporate some more then freeze again for a second crop of lesser quality (considering everyone wants to see them big crystals recrystalization is a must, you can combine the solids or recryst separately if the second one has an obvious drop in quality)

Thanks alot for your detailed reply.
However, this only raises more questions. The saying the more you know, the less you understand goes up I guess.

Lets jump on-topic.

What makes the product dissolve? And this is useful advice.

What was the flaw?

So it would make more sense to make a solution acetone / HCI, and store it on freezer temp before acidifying. I'm going to try this.

Well, when I spoke to another respected member on this forum, and he said doing it my way was wrong. Yours is right.
But I want to know why, just copying other peoples methods may work, but i'm trying to understand why it works. Lol.

I also have a question regarding the ideal temp on DCM.
Currently i'm heating to 37 C half an hour after adding methylamine, and let the solution stir for 4 hours.

Have you, or any other contributors on this forum advice on the ideal heating temperature and time for methylamation on DCM, 1:5 ratio with ketone?

SonicNLyou can add all the methylamine at once it's nonsense you don't have to add it for an hour xD

mocnykutasYeah I used to do that on DCM

 

[RegulierTier]

I have 2 questions. The first question is: I don't quite understand the purpose of the bag. What is it for and how do I attach the bag? The second question is: Can I also use methylamine hydrochloride and prepare the solution according to the following calculation, so that I dissolve 0.2487 g of methylamine hydrochloride in 200 mL of water?
Provided I haven't miscalculated or made a mistake somewhere in my thinking.

 

[HerrHaber]

Your calculations are presumably correct but you still need to freebase the methylamine hydrochloride to obtain an aqueous solution of methylamine that will also have the alkaline chloride (Na in case of NaOH and K in case of KOH) in equimolar amount therefore your aq solution will be to the same extent methylamine and Alkaline chloride (the percentage of methylamine in that water can't possibly be 40% since there is an equal amount of say NaCl).
The bag question is a silly one but I'm feeling you why it got you confused, the jar may not be completely sealed by it's own lid alone so the purpose of the bag placed in between the top of the jar and its lid is to form a tighter seal so that the MeNH2 gas can not escape the reaction enclosure, for the same reason people also put tape around the closure.
I hope this is disambiguating rather than further complicating things for you. Feel free to ask for more detailed explanation and I promise to do my best to explain it all over again which is better than you doing misstakes.
Cheers!
