The condensation of 3-methylphenol (I) and epichlorohydrin (II) by means of NaOH gives 1,2-epoxy-3-(3-methylphenoxy)propane (III), which is then condensed with 3,4-dimethoxyphenylethylamine (V) by heating their mixture at 95-100 C.
The condensation of 3-methylphenol (I) with epichlorohydrin (II) by means of a catalytic amount of piperidine gives 1-(3-methylphenoxy)-3-chloro-2-propanol (IV), which is then condensed with 3,4-dimethoxyphenylethylamine (V) by heating their mixture at 95-100 C.
