Stage one: 1-Phenylpropan-1-one Bromination
Stage two: Preparation and Washing of Methcathinone Hydrochloride
Stage three: Methcathinone Hydrochloride Formation

Edit: 6:20 - 125 ml of ethyl acetate

methcathinone synthesis is identical to 4mmc, only we use 2b1m. Here you can clearly see that the free base has been overheated and a red-green free base remains, which means there is no complete reaction with bromoketone. Yellow means pure free base. There is too little DCM in the amination reaction. Moths disagree. The rest is fine. Ps. methactinone should be as white as milk after adding hydrochloric acid. then you don't need to clean it with acetone and you have pure methatynon hcl

Watch the video carefully. You don't understand the process well enough.
What is a red-green base?
Why do you need more DCM?
When acidified, methcathinone dissolves immediately in water.
Byproducts that affect color are quite common in synthesis. That doesn't make the synthesis a failure. It can be purified.

The video shows a chemical experience. There is no need to take it as something permanent. There can be many different situations and many solutions in the synthesis process.
Every chemist faces many problems, and almost every problem has a reasonable solution.
Experts of our forum are ready to help with synthesis in various difficulties.

I'm so happy to see this. While I know the synthesis of methcathinone and mephedrone are extremely similar, I'm excited for methcathinone to receive more attention.

It seems like an interesting drug, just no popular, but I bet if this gets going and it is actually a decent drug, it might become a bit more popular.
 
Methcathinone is a precursor to ephedrine. This is generating a certain amount of interest in it.
Methcathinone is well distributed in African countries, and perhaps Africans could benefit from this synthesis. We are happy to help if anyone has any questions about the synthesis.
The syntheses of mephedrone and methcathinone are similar and the difference is the main precursor. In the synthesis of methcathinone, the starting precursor is propiophenone/2-bromopropiophenone. And in the synthesis of mephedrone, the starting precursor is 4-methylpropiophenone/2-bromo-4methylpropiophenone.

I doubt this will ever take off except perhaps in very large scale.

You are basically doing a multistep synthesis to get to a precursor for meth. You'll still have to react the ephedrine as per typically done, after resolving it...so you don't even save on the resolution step.

P2p will always be king unless the black market starts producing ephedrine via bacteria like done in the pharmaceutical industry

Otherwise, it's more steps, using more methylamine, and more work than synthesizing p2p, imo
 
Hello does anyone have any information regarding synthesis of methamphetamine using "hypo cook" synthesis route.By the way I am really struggling a lot to find an convenient method to synthesize methamphetamine the issue is with the p2p I am not able to find those chemicals needed to synthesize p2p here in india I am fed up with this I will be frank I am not an chemist but I really do wanna learn how to synthesize methamphetamine I been into this for like months but still I can't find an convenient synthesis route I messaged a lot of members in this forum but none replied I don't even have btc wallet to purchase ethyl2chloropropionate and other precursors to synthesize p2p. I don't have enough of money for it please let me know if anyone have "hypo cook" cook synthesis route atleast give me an reply

As an African yes you are right,The most Populer drugs 1) Crystal Meth 2) methaqualone (Extremlely Cheap) 3)CAT

They are 1 and the same thing.
