4-MMC (mephedrone) synthesis in DCM

[TheEnthusiasticCat]

I think 300ml DCM is plenty for this amount of BK4, 500ml in my opinion is too much and you could be saving money instead.

How long does your crystallisation take out of curiosity?

Hope you're well.

Took 1 day for me

Thank you, i can see your crystals?

How do you get crystals so quickly?

 

[4synergy]

with the cold method and 50/50 IPA and d-water

 

[Albert13]

Do you mean crystallization in the refrigerator?

 

[4synergy]

Yes

Hey guys, I had solution before crystalization slightly pink/ orange. Now crystals are also slightly orange. How actually work cleaning with second crystalization? Dirt won't evaporate... Or ?
Edit: worked with DCM..

Hi Guys ! I need some help.
So the problem is that I didnt follow the steps correctly but Ive got smth out of it. hope we can repair it...
I added liquid 2b4m - 200 ml + dcm 200 ml + methylamine 40% 400 ml.

1. I added liquid 2b4m - 200 ml + dcm 200 ml + methylamine 40% 400 ml.
2. The solution was stirred for 2 hours and was coling the solution in water bath to keep it from overheating. the temp was 30-40. I was checkig constantly.
3. After 2-2,5 hours if reaction i made the acidification and removed the top layer

4. I have dried it/evaporated in the oven at 40-50 celsius until Ive got white powder as shown on the attachements

I tried a row and gave out some samples : It deffinately has some stimulant effect but it burns so hard the nose that its a complete catastrophy.
In comparation to regular MEF its very weak.

Guys, can I repair or finalize this powder to make smth more close to mephedron ?
thx

I gues guys, that I've found out the mistake.
I was driing the upper transparent layer, the methylamine liquid insted of working with the oil... because it has seem so dirty.
I'll try again, hope someone will write me a good comment. I mean smth I can learn from.
thx

You will be alright
Sent a pic ounce you are done , with toluene and benzene , the mephredrone is on the lower layer , I guess with dcm the mephredrone in the end will be on the top layer
