Procedure

To a solution of 32 mg of 3-{2-methoxy-4-[4-methylsulfanylmethyl-2-(4-trifluoromethyl-phenyl)-thiazol-5-ylmethoxy]-phenyl}-4H-1,2,4-oxadiazol-5-one in 4 mL of dimethylformamide was added 15 mg of metachloroperbenzoic acid. The resulting mixture was stirred for 45 min at room temperature, then poured into water and extracted with dichloromethane. The organic extracts were washed with a saturated aqueous solution if sodium bicarbonate and concentrated under reduced pressure. The crude product was purified by column chromatography on silica gel (gradient of methanol in dichloromethane) to give 25 mg of 3-{4-[4-methanesulfinylmethyl-2-(4-trifluoromethyl-phenyl)-thiazol-5-ylmethoxy]-2-methoxy-phenyl}-4H-1,2,4-oxadiazol-5-one as a white solid which was further purified by trituration with diisopropyl ether.
