A mixture of ethyl 3-cycloheptyl-3-oxo-2-(2,4,6-trifluorophenyl)propanoate (342 mg, 1.0 mmol), 3-amino-1,2,4-triazole (84 mg, 1.0 mmol), and tributylamine (185 mg, 1.0 mmol) is stirred under nitrogen atmosphere at 160° C. for 2.5 h and cooled to room temperature. The mixture is dissolved in ethyl acetate and the organic layer is washed with 1.0 N hydrochloric acid and saturated sodium chloride, dried over magnesium sulfate, and concentrated to a solid. The solid thus obtained is washed with hexanes to give crude 7-cycloheptyl-6-(2,4,6-trifluorophenyl)[1,2,4]triazolo[1,5-a]pyrimidin-5-ol as a light tan solid (225 mg). MS: m/z 363.2 (M+H).
