Man, you're interested in the old method of making Jeff from ephedrine or pseudoephedrine by oxidizing it with potassium permanganate in an acidic environment, right? It's very simple. but wouldn't it be better to reduce it with hydrogen iodine in the presence of red phosphorus to...

I totally agree with you, friend. 3cmc somehow reminded me of a-pvp in terms of the method of isolation and crystallization. Due to the water in which hydrogen chloride is dissolved, they do not immediately crystallize from the solvent, but settle to the bottom in the form of an oily liquid...

Judging by this photo, buddy, you certainly have a talent for chemistry. Please accept my sincere congratulations. You are the best Bro ✊😉 and here is my first mephedrone cross. Only for some reason, chrome does not allow me to insert an image ... sad.🥺

Excuse me sir. I misunderstood you: "Do you need two solvents?" and "I don't heat them?"... I have nothing against this, but please explain why it was said: to the synthesis of 3cmc using the 4mmc synthesis technology as presented by Sir William, or is it your personal, successful experience in...

my respect! could you share your unique experience of obtaining 70% yield in the synthesis of 4mmc in DCM? This is an extremely interesting result, at least for me. I will be very grateful to you for the enlightenment.

My congratulations, friend! You're the best! After such great success in subjugating substances, could you share with your fans your unique experience of this synthesis? because I've been trying for about a month to get a meager but successful result in 3cmc synthesis, but so far I've only had...

Salute sir William! I carried out the synthesis of 3cmc from 2Br-3Clpropiophenon CAS 34911-51-8 in strict accordance with this manual with the only difference that I used DMSO instead of NMP, but the result is still not satisfactory. A glass with a mixture of all the components specified in the...

What's govern on?

quite detailed and clear answer, thank you very much. Armed with this information, I am going to conquer this substance right now.👋😉I will return with a shield, or on it.🤭

Based on this video, this synthesis uses 0.55mol (125g) BK-4 and 2.9mol (250ml*0.9g/ml*0.4=90g) methylamine. What caused the need for an almost sixfold excess of methylamine? And can this negatively affect the yield of the final product? Or maybe I'm wrong in my calculations?

my respect 👋 the fact is that I have 3-chloropropiophenone (cas: 34911-51-8) available, which differs from 4-chloropropiophenone only in that it is a liquid, but I want to get exactly 3-cmc. So thank you very much for your response to the previous post. And on this occasion, I have the last 2...

no buddy. this reaction is sn2, so you need a nucleophilic agent, and your ketone is not.

Dear Mr. Patton, I have a curiosity which you have advised me to satisfy. Can you explain which solvents to use and create conditions for the synthesis of Clephedron from 2-brom-3-chloropropiophenon? I understand that this synthesis is similar to the synthesis of Mephedrone, but the precursors...
