Procedure

A mixture of methyl 4-(7-acetyl-5-chloroquinolin-8-yl)piperazine-1-carboxylate (0.018 g, 0.052 mmol) and ammonium acetate (0.0399 g, 0.518 mmol) in methanol (0.2 mL) and acetonitrile (0.2 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 (0.13 mL, 0.13 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 C17H22ClN4O2 (M+H)+: m/z=349.1; Found: 349.1.
