Procedure

A mixture of 1-[5-chloro-8-(3-fluoropiperidin-1-yl)quinolin-7-yl]ethanone (0.0287 g, 0.0936 mmol) and ammonium acetate (0.0721 g, 0.936 mmol) in methanol (1.0 mL) and acetonitrile (1.0 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 (0.234 mL, 0.234 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 combined organic layers were dried over MgSO4 and concentrated to give the desired product. LCMS calculated for C16H20ClFN3 (M+H)+: m/z=308.1; Found: 308.1.
