실험 절차

To 1.0 g (3.4 mmol) of [3-(2,4-dichlorophenyl)phenyl] isopropyl sulfide in 50 ml of chloroform, 0.7 g (4.1 mmol) of m-chloroperbenzoic acid was added at 0° C. with stirring, and the reaction mixture was stirred for 2 hours. The reaction mixture was stirred at room temperature for another 12 hours, and 5% aqueous sodium bicarbonate was added for separation. The chloroform layer was washed with 5% aqueous sodium sulfite and water and dried over anhydrous magnesium sulfate, and the solvent was distilled off under reduced pressure. Purification of the residue by silica gel column chromatography afforded 0.9 g of [3-(2,4-dichlorophenyl)phenyl] isopropyl sulfoxide (yield 85.0%) as a colorless dough (nD20 1.6169).
