Reaction Steps

To a solution of 3-[4-(isopropylthio)phenyl]-2-methyl-5-{[2′-(5-oxo-4,5-dihydro-1,2,4-oxadiazol-3-yl)biphenyl-4-yl]methyl}-6-propylpyrimidin-4(3H)-one (0.28 g) in acetonitrile (3 mL) was added 3-chlorobenzenecarboperoxoic acid (0.26 g), and the mixture was stirred at 0° C. for 3 hr. Ethyl acetate, water and sodium thiosulfate were added to the reaction mixture, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine and dried over anhydrous magnesium sulfate. The solvent was evaporated and the residue was purified by silica gel column chromatography to give the title compound as a colorless solid (0.21 g, 71%).
