Procedure

A mixture of 1-(5-fluoro-8-{4-[(1-methyl-1H-pyrazol-4-yl)carbonyl]piperazin-1-yl}quinolin-7-yl)ethanone (0.045 g, 0.12 mmol) and ammonium acetate (0.0909 g, 1.18 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 C20H24FN6O (M+H)+: m/z=383.2; Found: 383.2.
