実験手順

To a solution of 3′-fluoro-4′-[(4-methyl-6-oxo-2-propylpyrimidin-1(6H)-yl)methyl]biphenyl-2-carbonitrile (1.4 g) and sodium acetate (0.32 g) in acetic acid (20 mL) was added bromine (0.2 mL), and the mixture was stirred at 70° C. for 2 hr. The reaction mixture was diluted with toluene and concentrated under reduced pressure. The residue was dissolved in ethyl acetate, 1 M aqueous sodium thiosulfate solution, washed with saturated aqueous sodium hydrogen carbonate solution and saturated brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography to give the title compound (0.65 g, 38%) as a colorless solid.
