Reaction Steps

A suspension of 4-(4-chlorophenyl)-3,3-dimethylpiperidin-4-ol (540 mg, 2.252 mmol) and benzaldehyde (0.274 mL, 2.70 mmol) in methylene chloride (15 mL) was treated with sodium triacetoxyborohydride (716 mg, 3.38 mmol), and the mixture was stirred overnight at room temperature. The mixture was concentrated in-vacuo. The residue was taken up in ethyl acetate, washed 3× with 1 N NaOH, once with brine, dried over sodium sulfate, and concentrated in-vacuo to yield the title compound (696 mg, 2.110 mmol, 94% yield) as a colorless oil. MS (ESI+)=330.14, (M+H)+.
