実験手順

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}cyclohexyl)oxy]acetate (1.1 g), 1N aqueous sodium hydroxide solution (10 mL), methanol (10 mL) and tetrahydrofuran (10 mL) was stirred at room temperature for 2 hr. The reaction mixture was adjusted to pH 4 with water (20 mL) and 1 N hydrochloric acid, 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. The obtained residue was purified by silica gel column chromatography to give the title compound as a colorless solid (0.9 g, 90%).
