Mephedrone (4-MMC) Synthesis [2B4M, Etyhyl Acetate, Methylamine HCl]

It would be awesome to have a video of this synthesis

There is one, in the video section. Exactly this

@gpatton please tell this noob(me) what role the NAOH and sodium bicarbonate play in this synthesis. Appreciate an answer.thanks

117.6% of the 2-b-4-mp amount. You write me the calculation. ( tip: it is the heavier element divided by the lighter one

As Hanna520 wrote in the another thread, it is better to prepare alc. methylamine for this synthesis. You will get fewer problems associated with the hydrolysis of ethyl acetate. You can use triethylamine, ethanol or methanol, or THF. Get a solution of gas and a precipitate of salts without water. It is easy to separate by decanting and you can start your synthesis more successfully. For small quantities this is usually not a problem, but if you want to synthesize several kg at a time it will be significantly different.

2b4m is bk ?
2i4m is ik im i right

 

[Naruto]

Yes

 

[Anarchy Labz]

I thought it was bk4, bk is 2b1m right?

thanks man

hello,
i sow in this post way for make reaction with Methylamine HCL ( no in 40% aqueous solution.
my question is because is more easy with hcl. Have differences with this dos ways?

is better follow the procedure with methylamine 40% aqueous solution prepared previously
or
add Metyliamine hcl directly to the mixture reaction like in this post

some one have tried both methods

Thanks for advanced

 

[Dr. MMX]

usage of hcl methylamine is inproper in that case, it releases more impurties into the mixture, but in the reality of really bad aq 40% that is used in the market i believe its better solution for the new chemists or ptacticants.
Its better to make it urself the aq from the hcl.

thanks so much
