Procedure

A mixture of 2-[4-(7-acetyl-5-chloroquinolin-8-yl)piperazin-1-yl]-N,N-dimethylacetamide (0.019 g, 0.051 mmol) and ammonium acetate (0.0391 g, 0.507 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 (0.12 mL). 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 C19H27ClN5O (M+H)+: m/z=376.2; Found: 376.2.
