Procedure

A solution of 2.164 g of 3-chloroperbenzoic acid (80%) in 150 ml of dichloromethane is dropped to a solution of 4.03 g of 4,5-bis(4-methoxyphenyl)-2-(4-methylphenylthio)imidazole in 100 ml of dichloromethane. The solution is agitated for 3 hours at room temperature, 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 3.71 g of 4,5-bis(4-methoxyphenyl)-2-(4-methylphenylsulfinyl)imidazole as an amorphous foam.
