Procedure

In 20 ml of acetic acid was dissolved 2 g of 5-{2-[2-(2-methoxyphenoxy)ethylamino]-1-phenylthioethyl}-2-methylbenzenesulfonamide and after adding thereto 0.5 ml of 30% H2O2, the mixture was heated to 50°-60° C. for 3 hours. After adding thereto 100 ml of water, the reaction mixture was extracted with 200 ml ofethyl acetate. The ethyl acetate extract was washed with an aqueous 1% sodium carbonate solution and then ethyl acetate was distilled off under reduced pressure. The residue was applied to a silica gel column chromatography, the product was eluted with a mixed solvent of chloroform and methanol (9:1 by volume ratio), and the colorless viscous oily productthus obtained was crystallized by the addition of ethyl acetate. The crystals formed were recovered by filtration to provide 1.3 g of 5-{2-[2-(2-methoxyphenoxy)-ethylamino]-1-phenylsulfinylethyl}-2-methylbenzenesulfonamide.
