실험 절차

To a solution of 7-(3-aminophenyl)-2-(4-phenoxyphenyl)-4,5,6,7-tetrahydro pyrazolo[1,5-a]pyrimidine-3-carboxamide (30 mg, 0.071 mmol) in DCM (2 mL) was added pyridine (0.2 mL). Then acryloyl chloride (6 mg, 0.084 mmol) was added dropwise. The mixture was stirred at RT for 0.5 hr and partitioned between DCM (20 mL) and brine (20 mL). Organic layer was separated from aqueous layer, washed with brine (2×20 mL), dried over Na2SO4 and purified by Pre-TLC (DCM/CH3OH=10/1) to afford 1.82 mg (5.38%) of 7-(3-acrylamidophenyl)-2-(4-phenoxyphenyl)-4,5,6,7-tetrahydropyrazolo[1,5-a]pyrimidine-3-carboxamide as a white solid. 1H NMR (400 MHz, CD3OD) δ 7.58 (d, J=8.8 Hz, 1H), 7.46 (d, J=8.8 Hz, 2H), 7.34-7.26 (m, 4H), 7.10 (t, J=7.6 Hz, 1H), 7.04-6.95 (m, 4H), 6.84 (d, J=7.6 Hz, 1H), 6.39-6.25 (m, 2H), 5.69 (dd, J=2.4, 9.6 Hz, 1H), 5.47-5.44 (m, 1H), 3.38-3.31 (m, 1H), 3.22-3.12 (m, 1H), 2.52-2.42 (m, 1H), 2.23-2.17 (m, 1H). MS (ESI) m/e [M+1]+ 480.
