Procedure

A mixture of 1-[5-chloro-8-(4-phenylpiperidin-1-yl)quinolin-7-yl]ethanone (0.0293 g, 0.0803 mmol) and ammonium acetate (0.0619 g, 0.803 mmol) in methanol (0.3 mL) and acetonitrile (0.3 mL) was heated at 65° C. in a sealed tube for 1 hour. After cooling to room temperature, to the resulting mixture was added 1.0 M sodium cyanoborohydride in tetrahydrofuran (0.20 mL, 0.20 mmol). The reaction was heated at 65° C. overnight. The mixture was cooled to room temperature, quenched with sat. NaHCO3 solution and extracted with dichloromethane. The organic layers were combined, dried over MgSO4 and concentrated to give the desired product. LCMS calculated for C22H25ClN3 (M+H)+: m/z=366.2; Found: 366.2.
