To a solution of ethyl 7-chloropyrazolo[1,5-a]pyrimidine-5-carboxylate (2.0 g, 8.9 mmol) in 15 mL DMSO were added (1-methyl-1H-pyrazol-4-yl)methanamine and triethylamine (2.69 g, 3.71 mL, 26.6 mmol), and the mixture was heated at 100° C. under microwave irradiation for 15 minutes. The reaction was then added to water (50 mL), and the precipitate was collected by filtration. The resulting white solid was carried forward without further purification. MS (Electrospray): m/z 301.2 (MH+).
