A mixture of 5-phenylpyrazin-2(1H)-one (0.86 g), N-bromosuccinimide (0.89 g) and DMF (16 mL) was stirred at room temperature for 2 hr. The reaction mixture was diluted with water, and the mixture was extracted with ethyl acetate. The extract was dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The residue was washed with hexane to give the title compound (0.18 g).
