실험 절차

To a solution of ethyl 5,7-dichloropyrazolo[1,5-a]pyrimidine-2-carboxylate (7.82 g, 30.1 mmol) in N,N-dimethylformamide (100 mL) was added 4-amino-tetrahydropyran (3.65 g, 36.1 mmol) and triethylamine (9.12 g, 90.2 mmol) at 0° C. The reaction mixture was stirred for 70 min at room temperature, and then pored into water. The resulting precipitate was collected to give ethyl 5-chloro-7-(tetrahydro-2H-pyran-4-ylamino)pyrazolo[1,5-a]pyrimidine-2-carboxylate. MS (APCI): m/z 325 (M+H).
