실험 절차

To a solution of N-(3-(5-cyano-2-methoxyphenyl)-1H-pyrazol-4-yl)pyrazolo[1,5-a]pyrimidine-3-carboxamide (200 mg, 0.56 mmol) in 3 mL of DMF was added 2-(chloromethyl)-1-methyl-1H-imidazole (109 mg, 0.84 mmol) and cesium carbonate (547 mg, 1.68 mmol). The reaction mixture was stirred at room temperature for 3 hours, then diluted with ethyl acetate and filtered. The filtrate was washed with brine, dried over magnesium sulfate, and concentrated. The crude product was purified by reverse phase HPLC and lyophilized to give 82.2 mg (32%) of N-(3-(5-cyano-2-methoxyphenyl)-1-((1-methyl-1H-imidazol-2-yl)methyl)-1H-pyrazol-4-yl)pyrazolo[1,5-a]pyrimidine-3-carboxamide. LCMS (ESI) m+H=454.1; 1H NMR (400 MHz, CDCl3) δ: 9.53 (s, 1H), 8.73 (dd, 1H), 8.64 (s, 1H), 8.48 (dd, 1H), 8.26 (s, 1H), 7.80 (d, 1H), 7.68 (dd, 1H), 7.06 (d, 1H), 6.97 (m, 2H), 6.83 (s, 1H), 5.42 (s, 2H), 3.85 (s, 3H), 3.63 (s, 3H).
