Procedure

To a solution of 24 mg of (2R)-1-{(2S,4S)-4-azido-1-(3,3,3-triphenyl-propanoyl)pyrrolidin-2-yl}carbonyl-N-{((3R)-1-cyclohexylmethyl-3-piperidyl)methyl}pyrrolidine-2-carboxamide in 0.5 ml of 20% hydrous tetrahydrofuran, 13 mg of triphenylphosphine was added at room temperature, followed by 3 hours' refluxing under heating. The reaction liquid was diluted with chloroform, washed with saturated aqueous sodium bicarbonate solution and dried over anhydrous sodium sulfate. Distilling the solvent off under reduced pressure, the resultant residue was purified by means of a preparative thin-layer chromatography (Kieselgel™ 60F254, Art 5744 (Merck), chloroform/methanol/28% aqueous ammonia=90/10/1) to provide 16 mg of the title compound in the form of a white solid.
