124 mg of tert-butyl 3-(ethoxycarbonyl)-4-[N-[(1RS,2RS)-2-(hydroxymethyl)-1-methyl-3-{5-(phenylcarbamoyl)-2-furyl}propyl]-N-(2-naphthylmethyl)carbamoyl]-4-(methoxymethyloxy)-3-butenoate was dissolved in 3 ml of chloroform and stirred with 288 mg of the Dess-Martin reagent (periodinane) at room temperature for 30 minutes. The reaction solution was poured into a mixture of saturated aqueous sodium hydrogencarbonate and saturated aqueous sodium thiosulfate and extracted with ethyl acetate. The organic layer was washed with saturated aqueous sodium chloride and dried over anhydrous magnesium sulfate. The desiccant was filtered off, and the solvent was distilled off under reduced pressure. The residue was purified by silica gel thin layer chromatography [Kieselgel™ 60F254, Art™5744; hexane/ethyl acetate=1/2] to give 65 mg (yield: 53%) of the title compound as a white solid.
