Under ice-cooling, 356 mg (0.84 mmol) of Des Martin periodinane was added to a solution of 65 mg (0.14 mmol) of N-[[1-[[[4-(4-morpholinylmethyl)phenyl]carbonyl]amino]cyclohexyl]carbonyl]-L-methioninol in 5 ml of methylene chloride, and the mixture was stirred for 1 hour. At the same temperature, 10 ml of ethyl acetate and 10 ml of a saturated aqueous sodium bicarbonate solution were added to the reaction solution. Sodium thiosulfate was added to the mixture until the solution became transparent, and the mixture was extracted with ethyl acetate. The organic layer was washed with a saturated aqueous sodium bicarbonate solution and saturated brine, and it was dried with anhydrous sodium sulfate. The solvent was distilled off under reduced pressure to obtain 55 mg (85%) of the title compound.
