Procedure

4′-[(4-{trans-4-[(2,5-Dihydroxypentyl)oxy]cyclohexyl}-5-oxo-7-propyl-4,5-dihydro[1,2,4]triazolo[1,5-a]pyrimidin-6-yl)methyl]biphenyl-2-carbonitrile (0.17 g) was dissolved in tetrahydrofuran (3 mL), triphenylphosphine (0.24 g) and then diethyl azodicarboxylate (0.40 g, 40% toluene solution) were added, and the mixture was stirred at room temperature for 18 hr. The reaction mixture was added to water, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography to give the title compound as a colorless solid (0.12 g, 74%).
