Mephedrone (4-MMC) synthesis; easy to perform- high yielding

[cartelloszetas]

Can made it much more faster and dont need use lab equipment. I see u made for fun if u will need made this way u need pay a lot monay for equipment.
U use also to much chemicals.
When u throw acid your powder need be white milf no like coffie. Of big scale u use too much acetone then and lost a lot of time too wash powder.
U can get 81% powder 75% crystal when u use dcm.

I would also be interested in your step-by-step procedure, mate

And also me

I want almost 1 kg of finished product. can I make it 3x the amount of reagents?

better to take x4 : 2Kg of bromoketone, some people don't even reach the 50% yield + if you want it in crystal form, your yield decrease

I recently achieved a greater than heard of yield of 4MMC hydrochloride in a moment when I expected it the least. Before I make it public to everyone I feel more than just 5 runs are necessary (out of 5, 2 consecutive were high yielding then 2 I thought I would improve but didn't, and another make's the triplicate required for me to state this). However I did run out of stuff and I'm looking forward to completely document this with pictures and all that. And not to be judged for holding back the "precious" information, I can trade off some counterintuitive details of the preparation:

-stirring is key (to keep DCM and water layers in the most intimate contact without phase transfer catalyst)
-relatively long reaction time (about 6 to 8h, I use taking a break by just pause the stirring assuming that if the layers are separate the reaction is almost halted)
-no heat applied (my third and fourth run had average and below yields when gentle heating was applied)
-cooling the mixture and reagents (at the acidification step chilled liquids were the best yielding)
-filter quick (just after the solids precipitate, do not let stay as part of the product will go in solution)

Hope this will help and I promise to be back with details and why not, a validation from another active member.

hello,
i'm not sure why condenser is used in this syntessis.
is correct that is for condense methylamine gas and keep it in the reaction

 

[Naruto]

No

 

[61-50-7]

yes, but as methylamine is already in excess I guess it's used to reduce the smell

 

[HerrHaber]

yes, but harmful even more so
