Оба варианта работают, и оба хороши.

Hi Marvin
Great video and I have successfully synthesized 4mmc using this synthesis, thanks. Worked beautifully when acidified with hcl35 but using hbr48 turned out to be a disaster..is hbr not interchangeable with hcl for acidification of 4mmc in benzene?

C10H11BrO + CH5N → C11H15NO + HBr
Как видно из уравнения, из одной молекулы 2-бром-4-метилпропиофенона получается одна молекула мефедрона.
C10H11BrO : 227,0977 г/моль
C11H15NO : 177,2429 г/моль
227.0977/177.2429=1.28127953
Коэффициент равен 1.28127953
Это означает, что из 100 г 2-бром-4-пропиофенона получится 78,0469818 г основания мефедрона.

Масса гидрохлорида мефедрона увеличится на 1,19 г/см3, а коэффициент составит 1,27273446.
C11H15NO+HCl=177.2429+1.19=178.4329
227.0977/178.4329=1.27273446

100g(C10H11BrO)/1.27273446=78.5709849g(C11H15NO)
Теоретический выход реакции 2-бром-4-метилпропиофенона составил 78,5709849 г гидрохлорида мефедрона. Но следует учитывать, что достичь теоретического выхода сложно, обычно потери составляют 20%.

Я нашел поставщика жидкого 2-бром-4-метилпропиофенона, но не знаю, с чего начать и сколько жидкости использовать для получения 100 г 4 ммк. Мне нужны советы.

Некачественная очистка или мало времени для реакции. Необходимо больше деталей.

Greetings

4mp to 4mmc successfully this way for me but starting 4mp was yellow so bromination done as per process.

Resultant mephedrone was a pasty powder and not crystal like salt as in video. Power was also low even after crystallization. Any thoughts on the pasty powder and low power. Yield was about 120 gms recrystallized from 400 ml 4mp.

Is there any way to purify the 4mp we get to start with or is that fine?

Would a superior product be possible if 4mp is brominated using NBs and PTSA, purified with a solvent nd then make the nmp synthesis from that 2b4m?

Thanks in advance. Tc

Я не добавлял ацетон, только MMC freebase в бензоле, и капнул 30 % HCl при pH 5,5. Я добавлял кислоту медленно. Может ли дело быть в ацетоне? Я забыл, потому что обычно я подкисляю с помощью DCM+вода, поэтому ацетон не пришел на ум. Как вы подкислили красоту на картинке? Спасибо большое.

Если вы используете соляную кислоту, вам нужен растворитель, который связывает воду. Это ацетон или спирт (этанол, пропанол).

Awesome tutorial!

I have question. Can be this tutorial used for 3-CMC or 3-MMC?

I'm using 2-bromo-4-methylpropiophenone for 4-MMC. What to use for 3-MMC?

@Marvin "Popcorn" Sutton can we scale this up using a 50litre batch reactor and drop the bromine Benzene mix from the reactors dropping funnel without any issues?
Bromine mix in an enclosed dropping funnel is a litle scary
