Following the procedures described in the Example 1, Step C, the reaction of 3-cyclopentanecarbonyl-3-phenylpropionaldehyde (1.36 mmol) and 1-(2-methoxyphenyl)piperazine (1.49 mmol) with sodium triacetoxyboranehydride (1.77 mmol) gave pure product 1-(2-methoxyphenyl)-4-[3-(cyclopentanecarbonyl)-3-(phenyl)propyl]piperazine (370 mg) in 67% yield. The di-hydrochloric acid salt was prepared as described above. m.p.=210-212° C.; MS (m/e): 406 (M+).
