Procedure

Sodium metaperiodate (0.28 g) is dissolved in water (4 ml) and thereto is added a solution of 1-{1-[4-(3-ethylthiopropoxy)benzoyl]-4-piperidinyl}-3,4-dihydrocarbostyril (0.4 g) in methanol (15 ml) and the mixture is stirred at room temperature overnight. The reaction mixture is concentrated and the residue is extracted with chloroform. The extract is dried with magnesium sulfate and the solvent is distilled off. The resulting residue is purified by silica gel column chromatography (solvent n-hexane ethyl acetate=1:2→ethyl acetate:methanol=20:1) to give 1-{1-[4-(3-ethylsulfinylpropoxy)benzoyl]-4-piperidinyl}-3,4-dihydrocarbostyril (0.12 g).
