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
După cum se poate observa din ecuație, o moleculă de 2-bromo-4-metilpropiofenonă produce o moleculă de mefedronă.
C10H11BrO : 227,0977 g/mol
C11H15NO : 177,2429 g/mol
227.0977/177.2429=1.28127953
Coeficientul este 1,28127953
Aceasta înseamnă că din 100 g de 2-bromo-4-propiofenonă, veți obține 78,0469818 g de mefedronă bază.

Masa clorhidratului de mefedronă va crește cu 1,19 g/cm3 și coeficientul va fi 1,27273446
C11H15NO+HCl=177.2429+1.19=178.4329
227.0977/178.4329=1.27273446

100g(C10H11BrO)/1.27273446=78.5709849g(C11H15NO)
Randamentul teoretic al reacției de 2-bromo-4-metilpropiofenonă a fost de 78,5709849g clorhidrat de mefedronă. Dar trebuie luat în considerare faptul că este dificil să se atingă randamentul teoretic, de obicei pierderea este de 20%.

Am găsit un furnizor de 2-Bromo-4-Metilpropiofenonă lichidă, dar nu știu cum să încep din acest punct și cât lichid ar trebui să folosesc pentru a face 100g de 4mmc.Am nevoie de câteva sfaturi.

Nu este purificat calitativ sau există puțin timp pentru reacție. Sunt necesare mai multe detalii.

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

Nu am adăugat acetonă, ci doar MMC freebase în benzen, și am picurat HCl 30% la pH 5,5. Am adăugat acidul încet. Ar putea fi acetona problema? Am uitat, pentru că de obicei acidific cu DCM+apă, deci acetona nu mi-a venit în minte. Cum ați acidificat frumusețea din imagine? Vă mulțumesc foarte mult.

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
