When proceeding as described in Example 2, but replacing 1-methyl-3-benzoyl-4-hydroxy-4-phenylpiperidine (used as starting material in said example) by 1-secondary butyl-3-benzoyl-4-phenyl-4-hydroxypiperidine and reacting 25 g. thereof with benzene in the presence of aluminum chloride, 17 g. of the crude base 1-secondary butyl-4,4-diphenylpiperidine are obtained. The crude base is not purified by distillation in a high vacuum but by adding ether saturated with hydrogen chloride to its solution in acetic acid ethyl ester. Thereby, the crystalline hydrochloride is precipitated. It melts at 242° to 245° C. (with decomposition) after recrystallization from acetic acid ethyl ester.
