4-MMC - Whats wrong here.

[Osmosis Vanderwaal]

So it seems the only things left are the reaction didn't reach the required temps, didn't react long enough or were under/ over protonated by the hcl. I too have failed this synth. Twice, matter of fact, in ethyl acetate. The last time I got crystals that looked right, had the right solvency in multiple solvents, melted at the right temperature and 8s identical to the product I was making except it had 0 potency. I'm making my own methylammonium chloride and refining it. I'm at a loss. The CH³NH²HCl looks different from the ammonium chloride. Puts off flammable gas when neutralized by NaOH+ water.... I don't get it. The 2-b-4-mp burns your eyes out and nose run while smelling like orange liquor. I'm lost too

I also one time tried in Ethyl Acetate and the product was not strong. I don't know, but maybe the ethyl acetate reaction is not a good route?

It's not warm in my basement and it takes a long time to dry. It's still wet

You claiming that you get yield over 100% from BK4 right?

 

[badboy345]

was 146g well.
is still wet but lost now 46g.
if dry can get 75g do 60g dry powder

What's up with you? You send me your pictures via DM, then post all the pictures here again... And now? I don't understand. The question was whether someone can tell me what went wrong here because I did everything as usual, except that I substituted benzene with DCM and strangely, no product precipitated. The procedure is the same as described in almost every second topic here and also the same one you described to me, except for the solvent.
Do you have anything useful to contribute or are you just trying to show off that you didn't have any problems? We've already discussed the same thing via DM, but so far, you couldn't pinpoint a mistake in my approach... So, I'm wondering what you're trying to communicate here.

Now, back to the topic... I've been thinking again and I realized that my solvent and methylamine were both very cold, coming straight from the refrigerator when I mixed them together. I'm not sure if that could be the reason because I heated the whole thing for 2.5 hours at 38°C with stirring, and even during the shake and bake attempt, enough heat was generated in the reaction. For my next attempt, I'll make sure my 2b4m/DCM solution and methylamine are at least at room temperature before mixing them.
Otherwise, I'll have to try again with a different solvent next time.
Does anyone else have any ideas? I just can't figure it out... Apart from substituting benzene with DCM, I've done nothing differently than usual and nothing different from what's described in many places in this forum.

show me and other people picture and say what do you do step by step. bro how somebody help u if dont see your work ??
Yes i show u is posible get made pure powder i use the same steps like on video with benzen and nmp. I no made on dcm but i thing is similar way.
I'm made 3 times only in my life made mmc. i use 4-methylenopropiophenone and brom and steps u have on the video.
u have also video with ethyl acetate and nmp only.
