Procedure

A mixture of N-[1-(7-acetyl-5-chloroquinolin-8-yl)piperidin-4-yl]methanesulfonamide (0.027 g, 0.071 mmol) and ammonium acetate (0.0545 g, 0.707 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 (0.17 mL, 0.17 mmol). The reaction was heated at 65° C. overnight. The mixture was cooled to room temperature, quenched with sat. NaHCO3 solution, extracted with dichloromethane, dried over MgSO4 and concentrated to give the desired product. LCMS calculated for C17H24ClN4O2S (M+H)+: m/z=383.1; Found: 383.1.
