After stirred at room temperature for 10 min, it was added Na(OAc)3BH (440 mg, 2.08 mmol) and was stirred for 30 min, the mixture was concentrated to remove most of the ACN, and the residue was diluted with CHCl3, organic layer was washed with Sat. NaHCO3, brine, dried and concentrated to give crude product, which was purified by column (DCM/MeOH=9:1) to give (1-methyl-5-phenyl-1,2,3,6-tetrahydropyridin-4-yl)methanol (140 mg).
