Procedure

A mixture of 4′-[(4-{trans-4-[(1-formylcyclobutyl)methoxy]cyclohexyl}-5-oxo-7-propyl-4,5-dihydro[1,2,4]triazolo[1,5-a]pyrimidin-6-yl)methyl]biphenyl-2-carbonitrile (0.7 g), sodium chlorite (0.21 g), sodium dihydrogen phosphate (0.15 g), 2-methyl-2-butene (0.53 mL), n-butanol (10 mL), tetrahydrofuran (5 mL) and water (5 mL) was stirred at room temperature for 16 hr. The reaction mixture was extracted with 1 N hydrochloric acid and ethyl acetate. The obtained ethyl acetate layer was washed with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography to give the title compound as a colorless solid (0.47 g, 65%).
