Procedure

To a solution (10 mL) of 1-[({trans-4-[5-oxo-6-{[2′-(5-oxo-4,5-dihydro-1,2,4-oxadiazol-3-yl)biphenyl-4-yl]methyl}-7-propyl[1,2,4]triazolo[1,5-a]pyrimidin-4(5H)-yl]cyclohexyl}oxy)methyl]cyclobutanecarboxamide (0.22 g) and pyridine (0.11 mL) in tetrahydrofuran was added trifluoroacetic acid anhydride (0.093 mL) at 0° C., and the mixture was stirred for 30 min. 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 amorphous solid (0.15 g, 69%).
