Procedure

To a solution (40 mL) of 4′-({5-oxo-4-[4-(prop-2-en-1-yloxy)cyclohexyl]-7-propyl-4,5-dihydro[1,2,4]triazolo[1,5-a]pyrimidin-6-yl}methyl)biphenyl-2-carbonitrile (2.7 g) and triethylamine (7.5 mL) in methylene chloride was added N-hydroxyethanimidoyl chloride (5 g) at 0° C. The reaction mixture was stirred at room temperature for 16 hr, washed with 1 N hydrochloric acid and then 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 (0.86 g, 28%).
