Reaction Steps

A mixture of ethyl trans-4-{6-[(2′-cyanobiphenyl-4-yl)methyl]-5-oxo-7-propyl[1,2,4]triazolo[1,5-a]pyrimidin-4(5H)-yl}cyclohexanoate (13 g), 2 N aqueous sodium hydroxide solution (50 mL), methanol (50 mL) and tetrahydrofuran (50 mL) was stirred at 50° C. for 3 hr. Water (20 mL) and 1 N hydrochloric acid were added to the reaction mixture, and the mixture was adjusted to pH 4, and extracted with ethyl acetate. The obtained ethyl acetate layer was washed 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 (11 g, 93%).
