Procedure

A mixture of 1-{5-chloro-8-[4-(2-fluorobenzoyl)piperazin-1-yl]quinolin-7-yl}ethanone (0.050 g, 0.12 mmol) and ammonium acetate (0.0936 g, 1.21 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 (0.30 mL, 0.30 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 C22H23ClFN4O (M+H)+: m/z=413.2; Found: 413.2.
