Procedure

A solution of 2.164 g of 3-chloroperbenzoic acid (80%) in 150 ml of dichloromethane is dropped to a solution of 4.46 g of 4,5-bis(4-methoxyphenyl)-2-(2-acetoamidophenylthio)imidazole in 100 ml of dichloromethane. The mixture is stirred for 3 hours at room temperature, the solution washed with sodium bicarbonate solution, dried over sodium sulfate, and concentrated to dryness under vacuum. The residue is chromatographed on 150 g of silica gel with acetone/hexane, thus obtaining 3.96 g of 4,5-bis(4-methoxyphenyl)-2-(2-acetamidophenylsulfinyl)imidazole as an amorphous foam.
