И двата варианта работят и са добри.

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
Както може да се види от уравнението, от една молекула 2-бромо-4-метилпропиофенон се получава една молекула мефедрон.
C10H11BrO : 227,0977 g/mol
C11H15NO : 177,2429 g/mol
227.0977/177.2429=1.28127953
Коефициентът е 1,28127953
Това означава, че от 100 g 2-бромо-4-пропиофенон ще получите 78,0469818 g мефедронова основа.

Масата на мефедроновия хидрохлорид ще се увеличи с 1,19 g/cm3 и коефициентът ще бъде 1,27273446
C11H15NO+HCl=177.2429+1.19=178.4329
227.0977/178.4329=1.27273446

100g(C10H11BrO)/1.27273446=78.5709849g(C11H15NO)
Теоретичният добив на реакцията на 2-бромо-4-метилпропиофенон е 78,5709849g мефедронов хидрохлорид. Но трябва да се има предвид, че е трудно да се постигне теоретичният добив, обикновено загубите са 20%.

Намерих доставчик на течност за 2-бромо-4-метилпропиофенон, но не знам как да започна оттук нататък и какво количество течност трябва да използвам, за да направя 100 г 4 ммс. имам нужда от съвети.

Да се направи това по следния начин. Не съм го направил. В течност. Добре. Пиперливи зърна

Не са качествено пречистени или имат малко време за реакцията. Необходими са повече подробности.

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

Не добавих ацетон, а само ММС свободна база в бензол, и капнах 30% HCl при рН 5,5. Добавих киселината бавно. Възможно ли е проблемът да е в ацетона? Забравих, защото обикновено подкиселявам с DCM+вода, така че ацетонът не ми дойде на ум. Как подкиселихте красавицата от снимката? Благодаря ви много.

Ако използвате aq. солна киселина, се нуждаете от разтворител, който свързва водата. Това е ацетон или алкохол (етанол, 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
