Procedure

A solution of 2.164 g of 3-chloroperbenzoic acid (80%) in 150 ml of dichloromethane is added dropwise to a solution of 4.23 g of 4,5-bis(4-methoxyphenyl)-2-(4-chlorophenylthio)imidazole in 100 ml of dichloromethane. The reaction mixture is agitated for 3 hours at room temperature, the solution is 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 3.90 g of 4,5-bis(4-methoxyphenyl)-2-(4-chlorophenylsulfinyl)imidazole as an amorphous foam.
