A mixture of 4′-[(4-{trans-4-[(3-methyl-4,5-dihydroisoxazol-5-yl)methoxy]cyclohexyl}-5-oxo-7-propyl-4,5-dihydro[1,2,4]triazolo[1,5-a]pyrimidin-6-yl)methyl]biphenyl-2-carbonitrile (0.4 g), dibutyltin oxide (0.088 g), azidotrimethylsilane (2.4 g) and toluene (25 mL) was stirred at 110° C. for 48 hr. The reaction mixture was diluted with ethyl acetate, washed with saturated aqueous potassium fluoride solution 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 amorphous solid (0.15 g, 35%).
