Here is a synthesis of propiophenone, which is then converted to methcathinone (ephedrone) and then to racemic ephedrine. Methcathinone and ephedrine from propiophenone Those who give up essential liberties for temporary safety deserve neither liberty nor safety Here is a similar transformation in which butyl nitrite is used. You can also use butyl nitrite in the synth. Or if you reduce it all, you have Amphetamine. Then reduce the oxime and you have Cathinone, if you can selectively reduce the oxime while not also reduceing the ketone. ![]() Propiophenone -> ISONITROSOPROPIOPHENONE (1,2-Propanedione, 1-phenyl-, 2-oxime) ![]()
