Procedure

A mixed liquid of 100 mg of 3-(2-cyanophenyl)-1-phenyl-5-bromo-1,2-dihydropyridin-2-one, 100 mg of 2-vinylpyridine, 6 mg of palladium acetate, 17 mg of tri-(o-tolyl)phosphine and 3 ml of triethylamine was stirred at 130° C. for 2 hours in nitrogen atmosphere. After cooling to room temperature, ethyl acetate was added thereto. The extract was washed with water and brine, and dried over magnesium sulfate. The solvent was evaporated, and the residue was purified by silica gel chromatography (ethyl acetate/hexane), to give 16 mg of the title compound as a white powder.
