thanks mate video was amazing. but i need to ask you that its really hard to find 4-methylpropiophenone this sht here. what can i do ? instead of this chic ?
4-MMC (mephedrone) synthesis. Complete video tutorial.

- Start date
I tried react 100g 2-bromo4methylpropiophenone with proportion 200ml methyloamine 40% and 300ml nmp. When last portion OF nmp was added, solution suddenly became yellow and clear, after 20min OF stirring it stays same, not browny and foggy like in the video. What I did wrong?

Your freebaasee is good what equipment u use

We brominate with the absorption of hydrobromic acid. Then we replace with methylamine and carry out the selection with further purification.
My synthesis takes approximately 3 hours from start to salt isolation. + crystallization.
Tried to crystallize in different ways. Nitrogen, thermoses, drying cabinets.

Can You specify Your synthesis? I want to obtain similar results. What equipment is needed etc

In order for mephedrone to come out correctly, you need to do all the steps correctly. In almost every method that I meet on the Internet, I find many wrong actions.
As a result, a person can receive 1 kg of mass, and after washing, lose up to 60-70%, and after crystallization, another part of the product.
Getting pure mephedrone hydrochloride snow-white powder, we crystallize in different ways. Sometimes a mixture of solvents sometimes gas chambers and a vacuum.
To be honest, I brominate 4-methylpropiophenone differently. I replace in 2 hours 30 minutes including cleaning.
If you have a mega powerful vacuum, you can overtake the base! But keep in mind, mephedrone, like all cathinones, does not like overheating! THEREFORE ONLY MEGAVACUUM! ))

After gaining access to the Research section, I will post an optimized synthesis of mephedrone with purity 99%+ and a yield close to 95% mole per 4-methylpropiophenone.
The technology is optimized for the kitchen and anyone who wants to have almost no smell will be able to receive mephedrone in huge quantities.
You have not tried this quality of mephedrone)

Bromination with hydrobromic acid is not convenient to scale, too much volume is needed (8.3 mol per liter only HBr), bromine is not convenient due to smell, bromine succinimide is too expensive and need Tos acid. You can use bromine + oxidizing agent, then the amount of bromine is half as much and there are no acid clouds...
Best way use cheap sources of bromine.
Do not make crystals weighing more than 5kg, it is very difficult to break with a hammer.

What you are saying is bromine isn't convenient due to smell, NBS due to price, HBr due to volume.
But you end up saying: oxydizing agent + cheap sources of bromine..
Half of bromine or cheap source smells exactly as worse

Questions:
1.Is reflux condenser necessary? if yes why?
2.Should everything be closed tight to methylamine do not espace? am i right?

Hi, you have to use it. Watch video please. It is used in order to avoid solvent and methylamine evaporation. In case of "shake and bake" style with small scale load, you can carry it out without condenser. It's up to you. Also, I recommend you to read topic about Glassware in Lab FAQ section to understand it better.
