실험 절차

To a solution of pyrazolo[1,5-a]pyrimidine-5-carbonitrile (2-2) (620 mg, 4.31 mmol) in NH3 in MeOH (5 mL) was added Raney Ni (100 mg). The reaction mixture was stirred at room temperature for 3 h under H2. The mixture was filtered, and the filtrate was concentrated to afford the title compound (600 mg). MS (m/z): 149 (M+1)+.
