Versuchsvorschrift
In 1 liter of dichloromethane was dissolved 67 g of 6-{3-[1-(2-methylphenyl)-2-imidazolylthio]propoxy}-3,4-dihydrocarbostyril. Thereto was added 32.6 g of m-chloroperbenzoic acid with ice-cooling. The mixture was stirred overnight. After the completion of the reaction, the reaction mixture was washed five times with an aqueous solution saturated with sodium hydrogencarbonate, dried with magnesium sulfate, and subjected to distillation to remove the solvent. The residue was purified by a silica gel column chromatography (eluant: dichloromethane/ethyl acetate/methanol=30/10/1). The crude crystals were recrystallized from ethanol-n-hexane to obtain 39.5 g of 6-{3-[1-(2-methylphenyl)-2-imidazolylsulfinyl]propoxy}-3,4-dihydrocarbostyril.
