A mixture of ethyl 3-cycloheptyl-3-oxo-2-(2,4,6-trifluorophenyl)propanoate (342 mg, 1.0 mmol), 2-aminoimidazole (Helv. Acta. Chim. 76, 2066 (1993)) (83 mg, 1.0 mmol), and 0.5 mL of tributylamine is stirred under nitrogen atmosphere at 160° C. for 1.5 h and cooled to room temperature. The mixture is dissolved in ethyl acetate and the organic layer is washed with 1.0 N hydrochloric acide (×2) and saturated sodium chloride, dried over magnesium sulfate, and concentrated to give crude 5-cycloheptyl-6-(2,4,6-trifluorophenyl)imidazo[1,2-a]pyrimidin-7-ol as a dark oil (294 mg).
