Reaction Steps

To an ice-cold solution of 2-(2,4-dichlorophenyl)-3-methyl-3-methylsulfinyl-1-(1,2,4-triazol-1-yl)butan-2-ol (Compound 30b, 346 mg) in chloroform (50 ml) was added m-chloroperbenzoic acid (350 mg), and the mixture was stirred at 0 to 10° C. for 1 hour. The reaction mixture was washed with aqueous ammonia and water, dried over magnesium sulfate and evaporated in vacuo. The oily residue was chromatographed on silica gel, eluting with chloroform, to give 2-(2,4-dichlorophenyl)-3-methyl-3-methylsulfonyl-1-(1,2,4-triazol-1-yl)butan-2-ol (120 mg) as crystals. Yield, 31.7 m.p., 209-210° C.
