NBS (0.62 g, 3.5 mmol) dissolved in DMF (5 mL) was added to a solution of 8-fluoro-3,4-dihydro-1H-quinolin-2-one (0.52 g, 3.2 mmol) in DMF (5 mL) dropwise at 0° C. The resulting reaction mixture was stirred at room temperature for 12 hr before it was treated with water. The precipitated solid was collected through filtration, washed with ether, and dried over vacuum to afford title compound (0.65 g, 85% yield) as a white solid. MS: 244.1 (M+H)+.
