Reaction Steps

To a solution of 4-chloro-1-(2,6-difluorophenyl)-2-oxo-1,2-dihydropyridine-3-carbonitrile obtained in Step E (670 mg) in N,N-dimethylformamide (5.0 mL) was added N-bromosuccinimide (548 mg) at room temperature. The reaction mixture was heated at 50° C. for 4 hr, and cooled to room temperature. To the reaction mixture was added water, and the mixture was extracted with ethyl acetate. The extract was washed with water, and dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (380 mg).
