Procedure
Following the procedures described in the Example 1, Step C, the reaction of 3-benzoyl-3-phenylbutyraldehyde (0.32 g) and 1-(2-methoxyphenyl)piperazine (0.23 g) with sodium triacetoxyboranehydride (0.33 g) gave pure product 1-(2-methoxyphenyl)-4-[3-(benzoyl)-3-(phenyl)butyl]piperazine (0.12 g). The oxalate salt was prepared as described above.
