A solution of 2.164 g of 3-chloroperbenzoic acid (80%) in 150 ml of dichloromethane is added dropwise to a solution of 3.90 g of 4,5-bis(4-methoxyphenyl)-2-(4-pyridylthio)imidazole in 100 ml of dichloromethane. The 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 recrystallized from ethanol/ether, thus producing 3.41 g of 4,5-bis(4-methoxyphenyl)-2-(4-pyridylsulfinyl)imidazole, mp 170°-171°.
