실험 절차

At −10° C., metachloroperbenzoic acid (789 mg) was added to a solution of 1-tert-butoxycarbonyl-4-[4-(2-pyridyl)benzoyl]piperazine (517 mg) in dichloromethane (dichloromethane: 8 ml). The resulting mixture was stirred for 24 hours, followed by dilution with dichloromethane. A small amount of an aqueous sodium thiosulfate solution and a saturated aqueous NaCl solution were added to the dilute solution. The organic layer so separated was washed with a saturated aqueous solution of sodium bicarbonate and a saturated aqueous NaCl solution and then dried over anhydrous sodium sulfate. The residue obtained by distilling off the solvent under reduced pressure was purified by chromatography on a silica gel column (dichloromethane:methanol=20:1), whereby the title compound (415 mg, 77%) was obtained.
