Reaction of 2-(o-aminophenethyl)-1-methylpiperidine with p-acetoxybenzoyl chloride in pyridine according to Example 1 provides 4-acetoxy-2'-[2-(1-methyl-2-piperidyl)-ethyl]benzanilide. Analytically pure product is obtained by crystallization from isopropyl ether, m.p. 88°-108° C. (corr.). The broad melting point of the analytically pure material is due to polymorphism.
