10 ml of a dimethylformamide solution containing 1 g of 3-nitro-1-phenyl-1,2-dihydropyridin-2-one was incorporated with 988 mg of N-bromosuccinimide, followed by stirring at room temperature overnight. Further, it was stirred at 50° C. for 3 hours. The reaction mixture was poured into ice-water, and the resulting precipitates were collected by filtration, to give 1.27 g of the title compound.
