3-CMC Synthesis Question

[Researcherr]

Forum community I ask for your help

Please I need advice which solvent to use in 3-CMC synthesis and how to make the crystalysation so crystals really form
I see people had problems with getting black oil at the end of reaction and crystals not crystalizing properly

Is synthesis any different then other cathinones? And which part is different?

 

[Researcherr]

@G.Patton Maybe you have any Informations?

Already found on the forum..
Just replace out the precursor with 2-bromo-3-chloropropiophenone for 3-CMC.
For 4-CMC 2-bromo-4-chloropropiophenone.

For crystallization you dont need more just: patience, clean water, IPA/EtOH, glass container, heating source. More time you wait the more pleasing the outcome will look.

24h only. Dont need wait weeks

 

[sleeplessmania]

Where did I mention weeks? Not wrote concrete duration, just mentioned the slower solvent evaporates the more likeable results will come out.

I think black oil is the result of too fast acidification. Also purify your powder. You can use the same crystallization method as for 4-MMC. Boil IPA and Demi 50/50, add product, want for it to dissolve and let the liquid evaporate. Crystals will form when more than 50% of the liquid is evaporated.

 

[mocnykutas]

colored solution during acidification is when you add hydrochloric acid too quickly and the solution starts to boil and produce impurities

 

[G.Patton]

Agree with you and guys above. Acidification is gentle procedure, don't hurry, stirr your free base solution well and check its pH. Avoid overheating.

 

[mocnykutas]

u need then get like it

 

[SonicNL]

4-MMC freebase drying. What yields you guys getting?

 

[mocnykutas]

U made crystal nie or u dry powder form liquid?

 

[SonicNL]

Drying from liquid

 

[mocnykutas]

I wash IT and will be pure white crystal

 

[SonicNL]

IPA and water?

 

[mocnykutas]

Only water

Anyone having pictures of end product ?

 

[Jesse_Pinkman_]

This is what i got

 

[leon]

Very nice crystals, how do you make?

 

[antrax]

Hi! my friend, How do you get transparent crystals after recrystallization?
I have synthesized methylone but after recrystallization I obtain orange-brown crystals and that I think means that the methylone crystals have impurities.
Thank you!!

I wrote my recipe in different threads, is not hard to find. But it took some time to get it done, sometimes they come out with some yellow color, then you have to wash and recrystallize. Water/ipa 50:50 oder 70:30
Then they become like this,

Many have recommended to use the same process documented for 4mmc. But the biggest difference is that you didn't use acetone to add HCL. Instead you used water? Then after PH of around 6 or 5.5 you separate the water that has the 3cmc salt dissolved in it and just let it evaporate?

I've tried the acetone method several times, but end up with a very dark purple solution when I add the cold acetone, like red wine. It goes dark before I even add the diluted HCL.

I cannot get the salt to crash out from it. I am using ethyl acetate as the solvent for the freebase. I always get to 5.5 ph and have it in the freezer for days, but no salt??
