Participants

Reaction Steps

A solution of 1-(3-Methoxy-4-nitrophenyl)-3,3-dimethylpiperidin-4-one (INTERMEDIATE 39) (278 mg, 1 mmol) and ammonium acetate (771 mg, 10.0 mmol) in MeOH (5 mL) was stirred at RT overnight. Sodium cyanoborohydride (75 mg, 1.2 mmol) were added. The reaction was stirred at RT for 2 h. MeOH (20 mL) and silica gel (5 g) was added. The mixture was concentrated in vacuo. The residue was purified by chromatography on silica gel (5% MeOH and 1% NH4OH in CH2Cl2) to give the title product (0.2 g, 72.0%).
