Procedure
A mixture of diethyl 2-{4-[4-(dimethylamino)butyl]-2,6-difluorophenyl]malonate (1.0 g, 2.7 mmol), 3-amino-1,2,4-triazole (250 mg, 3.0 mmol), and tributylamine (0.71 mL, 3.0 mmol) is stirred under nitrogen atmosphere at 160° C. for 16 h and cooled to room temperature. The mixture is stirred with 20 ml of hexanes. The precipitates are collected by filtration, washed with hexanes to give 6-{4-[4-(dimethylamino)butyl]-2,6-difluorophenyl}[1,2,4]triazolo[1,5-a]pyrimidine-5,7-diol as a white solid (795 mg). MS: m/z 362.1 (M−H).
