실험 절차

A mixture of N-[1-(2-bromoethyl)-3-[5-chloro-2-(difluoromethoxy)-phenyl]-1H-pyrazol-4-yl]pyrazolo[1,5-a]pyrimidine-3-carboxamide (200 mg, 0.39 mmol), triethylamine (394 mg, 3.89 mmol), ethyl 2-aminoacetate hydrochloride (271 mg, 1.94 mmol) in ethanol (20 mL) was stirred at 80° C. for 24 hours then concentrated under reduced pressure. The crude product was purified by high pH Prep-HPLC to afford the title compound as an off-white solid (31.9 mg, 15%). LCMS (Method 14) [M+H]+=534.2, RT=1.13 min. 1H NMR (300 MHz, CD3OD-d4) δ: (ppm) 9.11 (dd, J=1.5, 7.0 Hz, 1H), 8.66-6.65 (m, 2H), 8.36 (s, 1H), 7.68 (d, J=2.4 Hz, 1H), 7.58 (dd, J=2.7, 8.7 Hz, 1H), 7.42 (d, J=8.7 Hz, 1H), 7.39 (dd, J=4.5, 7.2 Hz, 1H), 6.55 (t, J=73.5 Hz, 1H), 4.35 (t, J=5.7 Hz, 2H), 4.17 (q, J=7.2 Hz, 2H), 3.41 (s, 2H), 3.15 (t, J=6.0 Hz, 2H), 1.25 (t, J=7.2 Hz, 3H).
