Procedure

The 4-(4-bromo-5,7-difluoro-3-methylquinolin-2-yl)piperazin-2-one (89 mg, 0.25 mmol) was dissolved in THF (2.0 mL). To the solution was added sodium hydride (30.0 mg, 1.25 mmol) (60% dispersion) followed by addition of 2-iodopropane (750 μL, 7.50 mmol). The reaction was heated to reflux and stirred overnight. The reaction was quenched with water and the mixture was extracted with EtOAc (2×50 mL). The combined organic layers were washed with brine (1×25 mL) and dried over magnesium sulfate. The crude product was purified by medium pressure chromatography (silica gel, 0 to 80% EtOAc:hexanes) to give 4-(4-bromo-5,7-difluoro-3-methylquinolin-2-yl)-1-isopropylpiperazin-2-one. Mass Spectrum (ESI) m/e=400.1 (M+1).
