実験手順

A mixture of 4′-[(5-oxo-4-piperidin-4-yl-7-propyl-4,5-dihydro[1,2,4]triazolo[1,5-a]pyrimidin-6-yl)methyl]biphenyl-2-carbonitrile (453 mg), ethyl bromoacetate (184 mg), potassium carbonate (276 mg) and N,N-dimethylformamide (5 mL) was stirred at 60° C. for 16 hr. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The extract 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 chromatography [eluent: hexane/ethyl acetate=60/40→35/65 (volume ratio)] to give the title compound as a colorless amorphous compound (418 mg, 80%).
