실험 절차

A mixture of 37.96 g (0.10 mole) of 3-[(4-chlorophenyl)thio]-1-[(4-methylphenyl)sulfonyl]piperidine, 300 ml of glacial acetic acid, and 61.8 g of 30% hydrogen peroxide (0.6 mole) was stirred overnight at 90° C. The reaction mixture was cooled to room temperature and diluted with ice water. The diluted mixture was made alkaline with 50% aqueous sodium hydroxide and extracted with methylene chloride. The aqueous phase was discarded. The methylene chloride phase was washed with sodium sulfite to remove traces of peroxide. The methylene chloride solution was dried over magnesium sulfate, filtered and the solvent removed in vacuo to give a yellowish white solid. Recrystallization of an aliquot of the solid from methylene chloridehexanes gave the product, m.p. 186°-187° C. in 57.2% overall yield.
