実験手順

To a solution of N-(3-(5-cyano-2-methoxyphenyl)-1H-pyrazol-4-yl)pyrazolo[1,5-a]pyrimidine-3-carboxamide (144 mg, 0.40 mmol) in 3 mL of DMF was added 5-(chloromethyl)-1-methyl-1H-pyrazole (78 mg, 0.6 mmol) and cesium carbonate (391 mg, 1.20 mmol). The reaction mixture was stirred at 60° C. for 6 hours, then cooled to room temperature, 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 58.3 mg (32%) of N-(3-(5-cyano-2-methoxyphenyl)-1-((1-methyl-1H-pyrazol-5-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: 9.58 (s, 1H), 8.74 (dd, 1H), 8.64 (s, 1H), 8.48 (dd, 1H), 8.21 (s, 1H), 7.81 (s, 1H), 7.69 (dd, 1H), 7.39 (s, 1H), 7.07 (d, 1H), 6.96 (dd, 1H), 6.31 (s, 2H), 5.33 (s, 2H), 3.86 (d, 6H).
