Procedure

3-[3-(3-Phenoxyphenyl)-4,5-dihydroisoxazol-5-yl]propanal (27.1 mg, 0.087 mmol), 1-(diphenylmethyl)piperazine (20.0 mg, 0.078 mmol), molecular sieve (5 beads) and NaBH(OAc)3 (50.0 mg, 0.237 mmol) were reacted in 3 mL of methylene chloride for about 12 hr. With the following processes the same as in Example 1, 20.2 mg (53.3%) of the target compound was obtained.
