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

[siko]

hello
9. Sodium bicarbonate 5% H2O solution 300 ml was poured into flask with freebase then stirred for 30 mins. After that layers are
how much Sodium bicarbonate do you put in the recipe?

you must not use soda on any step of 4mmc, it is produce more problems than solutions, all you need is wash wash wash.
bromination ccan be done with 100% yields with clean result, amination...yes, only 3-5x waterwash, acidation, again, can be done clean way, but at least one wash is must.

Thank you for interest in the topic, but its the topic about final reaction from the 2b4m,
Synthetise of 2b4m should be discussed under its topic. Dont mess with peoples minds and discuss the following reaction here only.

hello Dr. MMX do you know where i can buy methytlamine hcl

​

 

[siko]

not understand sorry what do you get from this ? 4-mmc or 2b4m

​

 

[ghostimage]

bk4 - 2b4m, i point to this in the end

 

[siko]

hello does anyone know where i can buy it ?

Methylamine HCl​

 

[Dr. MMX]

We do have reagents market, please check it out.

 

[siko]

ok thank you

 

[siko]

thank you

Reagents:

Consider 50 % yield (it could be more but also less if mistakes are made) so take any recipe that starts with 100 g BK4 and go x10. But to cook it in one batch you'll need to think more about temperature control especially while adding methylamine, stirring that volume etc. Also, acidification in aqueous environment without acetone is something to consider, it saves on reagents and is good for the yield too, but may take longer to obtain finished product depending on your options for drying and crystallization.
