실험 절차

A suspension of 4-chloro-N-methyl-2,2-diphenylbutyramide (1.4 g, 0.005 mol), 4-p-chlorophenyl-4-piperidinol (2.12 g, 0.01 mol), and trace Kl in i-BuCOMe (50 ml) was refluxed for 12 hrs. The reaction mixture was worked-up as described in Example 16 to provide 4-(p-chlorophenyl)-4-hydroxy-N-methyl-α,α-diphenyl-1-piperidinebutyramide hydrochloride (0.8 g, 35%), mp 236-238° C.
