Procedure

to a stirred mixture of 4.4 parts of 1-(1-methylethyl)-N-phenyl-4-piperidinamine, 5.3 parts of sodium carbonate and 180 parts of benzene are added dropwise 5 parts of benzeneacetyl chloride. Upon completion, stirring is continued overnight at reflux. The reaction mixture is cooled, washed successively with water, a sodium hydrogen carbonate solution and again with water, dried, filtered and evaporated. The residue is converted into the hydrochloride salt in 2,2'-oxybispropane and 2-propanol. The formed salt is filtered off and crystallized from a mixture of 2-propanol and 2,2'-oxybispropane, yielding 2.5 parts of N-[1-(1-methylethyl)-4-piperidinyl]-N-phenylbenzeneacetamide hydrochloride; mp. 184.4° C.
