Question how long the bromination of propiophenone takes? ( methcathinone project )

[icebrg1337]

hello everyone

i want to know how long the bromination of propiophenone takes in this video: Methcathinone HCl Synthesis From Propiophenone
in stage 1: I'm not sure if i have to stir it for 1 day or 1 hour is just enough...
in stage 2: after the bromination process and after adding methylamine, we have to stir it for at least 24 hours
in stage 3: how long it takes for the methcathinone freebase to react with HCL to form the HCL salt of methcathinone?

thank you so much.

Depends if you use a solvent and what method you use.

I've done the HbR h2o2 route overnight + day. dropwise addition, stirring overnight and day. check every couple hours.

If you have Elemental bromine and using a solvent it can be done in 30/45 minutes .

For me the former method takes longer but feels better in every way

Woops. You're asking propiophenone. Sorry.

Should work about the same though
