Procedure

To a solution of 6-{[2′-(5-oxo-4,5-dihydro-1,2,4-oxadiazol-3-yl)biphenyl-4-yl]methyl}-7-propyl-4-[trans-4-(3,3,3-trifluoro-2-hydroxypropoxy)cyclohexyl]pyrazolo[1,5-a]pyrimidin-5(4H)-one (0.14 g) in methylene chloride (2 mL) was added 1,1,1-tris(acetyloxy)-1,1-dihydro-1,2-benziodoxol-3-(1H)-one (0.14 g), and the mixture was stirred for 3 hr. Ethyl acetate, water and sodium thiosulfate were added to the reaction mixture, and the mixture was stirred for 30 min. After stirring, the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate, and the solvent was evaporated. The residue was purified by silica gel column chromatography to give the title compound as a colorless amorphous solid (0.098 g, 73%).
