Participants

Reaction Steps

To a mixture of 4′-({4-[2-(4-fluorophenyl)-2-hydroxyethyl]-5-oxo-7-propyl-4,5-dihydro[1,2,4]triazolo[1,5-a]pyrimidin-6-yl}methyl)biphenyl-2-carbonitrile (0.78 g), 2,6-lutidine (0.27 mL) and tetrahydrofuran (20 mL) was added tert-butyl(dimethyl)silyl trifluoromethanesulfonate (0.53 mL), and the mixture was stirred at room temperature for 5 hr. The reaction mixture was diluted with ethyl acetate, washed with saturated aqueous potassium hydrogensulfate 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 solid (0.56 g, 58%).
