実験手順

In 20 ml of chloroform was dissolved 900 mg of 2-[2-(isobutylamino)benzylthio]imidazo[4,5-b]pyridine. To the resulting solution was portionwise added under chilling with ice 618 mg of m-chloroperbenzoic acid (purity: 80%) over a period of 30 min. To the mixture was added a saturated NaHCO3 solution, and the resulting mixture was then stirred. The organic phase was separated and extracted successively with 20 ml of 0.1N NaOH and 10 ml of 0.1N NaOH. The alkaline extracts were combined and neutralized by NH4Cl, and the deposited oil was extracted with chloroform. The chloroform extract was washed with a saturated aqueous sodium chloride solution, dried over sodium sulfate and placed under reduced pressure to distill off the solvent. The residue was crystallized by addition of diethyl ether. The crystalline product was washed with diethyl ether to give 195 mg of 2-[2-(isobutylamino)benzylsulfinyl]imidazo[4,5-b]pyridine as a pale yellow crystalline powder. m.p.: 116° C. (decompn.).
