Reaction Steps

A mixture of 0.96 parts of 1-(2- ethoxybenzoyl)aziridine, 1.06 parts of 4-(4-chlorophenyl)-4-piperidinol, 5.4 parts of benzene and 0.8 parts of methanol is stirred and refluxed for 2 hours. The reaction mixture is cooled. Upon the addition of 1,1'-oxybisethane, the product is precipitated. It is filtered off, crystallized from 2-propanol, filtered off again and dried overnight in vacuo at 80° C, yielding 1.4 parts of N-{2-[4-(4-chlorophenyl)-4-hydroxy-1-piperidinyl]ethyl}-2-ethoxybenzamide; mp. 171°-173° C.
