A mixture of 4′-({4-[trans-4-(2-hydroxyethoxy)cyclohexyl]-5-oxo-7-propyl-4,5-dihydro[1,2,4]triazolo[1,5-a]pyrimidin-6-yl}methyl)biphenyl-2-carbonitrile (1.2 g), triethylamine (0.38 mL), methanesulfonyl chloride (0.21 mL), N,N-dimethylpyridin-4-amine (0.028 g) and acetonitrile (20 mL) was stirred at room temperature for 3 hr. The reaction mixture was washed with water 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 (1.2 g, 89%).
