Procedure

Under ice-cooling, 15 ml of a dimethylformamide solution containing 1.50 g of 1-(2-pyridyl)-1,2-dihydropyridin-2-one was incorporated with 1.60 g of N-bromosuccinic acid imide. The mixture was stirred at room temperature for 2 hours, and then diluted with water and extracted with ethyl acetate. The organic layer was washed with water and brine, and then dried over magnesium sulfate. The solvent was evaporated, and the residue was purified by silica gel chromatography (ethyl acetate/hexane=1:3), to give 1.13 g of the title compound as a pale brown powder.
