Procedure

To a solution of (2R)-2-t-butoxycarbonylamino-2-methyl-4-[5-(5-phenylpentanoyl)furan-2-yl]butan-1-ol (110.2 mg, 0.26 mmol) obtained in Example (29a) in dichloromethane (2.6 ml) was added Dess-Martin reagent (165.0 mg, 2.28 mmol), and the resulting mixture was stirred at room temperature under a nitrogen atmosphere for 1 hour. After stirring, the reaction mixture was evaporated in vacuo, and to the residue was added a 10% aqueous sodium thiosulfate solution to decompose the excess reagent. The resulting mixture was extracted with dichloromethane, and the extract was washed successively with saturated aqueous sodium hydrogencarbonate solution and saturated aqueous sodium chloride solution and dried over anhydrous magnesium sulfate. After filtration, the solvent was removed in vacuo, and the residue was purified by chromatography on a silica gel column using a mixed solvent of hexane and ethyl acetate (3:1) as the eluent to afford the title compound (105.9 mg, yield: 97%).
