Versuchsvorschrift
A mixture of 1-[5-chloro-8-(3-methoxypiperidin-1-yl)quinolin-7-yl]ethanone (0.0373 g, 0.117 mmol) and ammonium acetate (0.0902 g, 1.17 mmol) in methanol (0.5 mL) and acetonitrile (0.5 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 (0.29 mL, 0.29 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 C17H23ClN3O (M+H)+: m/z=320.2; Found: 320.1.
