Procedure

3-Chloroperoxybenzoic acid (3 eq, 2.5 mmol, 424 mg) was added to a solution of (+)-3,4-dihydro-3-[(dimethylamino)carbonyl]-2-[[(4-methoxyphenyl)methyl]thio]-6-methyl-4-(3-nitrophenyl)-5-pyrimidinecarboxylic acid, 1-methylethyl ester in dry dichloromethane (8.2 ml) at 0° C. under a nitrogen atmosphere. The reaction was stirred overnight at room temperature, and a precipitate formed. The mixture was diluted with ethyl acetate (15 ml) and washed with 1N hydrochloric acid (twice), 1N sodium hydroxide (twice) and water. The combined organic layers were dried over magnesium sulfate, filtered, and reduced in vacuo to afford an oil, 390 mg.
