Methcathinone is just as hard to come by as is ephedrine or even pseudoephedrine now that the RC World started going down the cathinone route a while ago now…

Hi all,

If I can, I would like to use this method for the synthesis of ephedrine for d-methamphetamine synthesis. I am aware that I will need to seperate the isomers of the methamphetamine produced in this case as the ephedrine we end up with in this synthesis is racemic.

Me and my team are planning on working on a method to scale up this synthesis.

Would it be faster and more efficient to manufacture methamphetamine from this synthesis method + the seperation of the 2 isomers or should we work on scaling up the method below:


to get d-methamphetamine straight away?

Thank you to whoever replies to this.

ConsiderYes, but you need to use any other appropriate carboxylic acid to separate isomers anyway.
