Procedure

To a mixture of 4′-[(3-butyl-5-oxo-1,5-dihydro-4H-1,2,4-triazol-4-yl)methyl]biphenyl-2-carbonitrile (1.00 g) and N,N-dimethylformamide (15 mL) was added 60% sodium hydride (0.60 g), and the mixture was stirred at room temperature for 30 min. To the mixture was added (2-bromoethyl)benzene (2.22 g), and the mixture was stirred at room temperature for 4 hr. The reaction mixture was diluted with ethyl acetate, washed with water and then 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 (0.72 g, 55%).
