실험 절차

N-(3-(5-cyano-2-methoxyphenyl)-1H-pyrazol-4-yl)pyrazolo[1,5-a]pyrimidine-3-carboxamide (120 mg, 0.334 mmol), 3-(chloromethyl)-4-methyl-4H-1,2,4-triazole (65 mg, 0.5 mmol) and Cs2CO3 (325 mg, 1 mmol) were suspended in DMF. The mixture was stirred overnight at room temperature, then filtered and concentrated in vacuo. The residue was purified by preparative HPLC to afford N-(3-(5-cyano-2-methoxyphenyl)-1-((4-methyl-4H-1,2,4-triazol-3-yl)methyl)-1H-pyrazol-4-yl)pyrazolo[1,5-a]pyrimidine-3-carboxamide (23.2 mg, yield: 15%). 1H NMR (CDCl3, 400 MHz) δ: 9.59 (s, 1H), 8.77 (dd, J=2.0, 7.2 Hz, 1H), 8.70 (s, 1H), 8.51 (dd, J=2.0, 4.4 Hz, 1H), 8.39 (s, 1H), 8.11 (s, 1H), 7.82 (d, J=2.0 Hz, 1H), 7.73 (dd, J=2.0, 8.4 Hz, 1H), 7.10 (d, J=8.4 Hz, 1H), 6.99 (q, J=4.4, 6.8 Hz, 1H), 3.91 (s, 3H), 3.72 (s, 3H).
