Synthesis of ephedrine from propiophenone
THEORY OF SYNTHESIS OF EPHEDRINE. The mechanism of these reactions is well known: - at the first stage, bromine is attached to propiophenone in benzene, alpha-bromine-propiophenone is obtained; - at the second stage, bromine is replaced by an amino group, cathinone is obtained (if ammonia is...- HIGGS BOSSON
