실험 절차

4-(6-bromopyrazolo[1,5-a]pyrimidin-3-yl)-N-(2,2,2-trifluoro-1-pyridin-2-ylethyl)thiophene-2-carboxamide (1 eq) was mixed with quinolin-6-ylboronic acid (1.3 eq). Dioxane (10 mL) and 1M Na2CO3 (2 eq) were added. The mixture was evacuated and flushed with nitrogen under stirring, then a solution Pd(Ph3P)4 (0.05 eq) in dioxane was added under inert gas. The temperature was brought to 100° C. The reaction mixture was stirred at this temperature overnight. The reaction mixtures were filtered through Celite, and the latter was washed with methanol. Purification by reverse phase LC gave 4-(6-quinolin-6-ylpyrazolo[1,5-c]pyrimidin-3-yl)-N-(2,2,2-trifluoro-1-pyridin-2-ylethyl)thiophene-2-carboxamide. 1H NMR (400 MHz, DMSO-d6): 6.11-6.22 (1H, m), 7.47-7.52 (1H, m), 7.67 (1H, dd, J=8.3 Hz, J=4.4 Hz), 7.81 (1H, d, J=7.8 Hz), 7.93-7.98 (1H, m), 8.19 (1H, d, J=8.8 Hz), 8.32 (1H, d, J=1.2 Hz), 8.34 (1H, dd, J=8.8 Hz, J=1.95 Hz), 8.48-8.53 (1H, m), 8.59 (1H, d, J=1.95 Hz), 8.67-8.70 (1H, m), 8.72 (1H, s), 8.76 (1H, d, J=1.2 Hz), 9.00 (1H, dd, J=4.4 Hz, J=1.7 Hz), 9.26 (1H, d, J=2.2 Hz), 9.54 (1H, d, J=9.3 Hz), 9.71 (1H, d, J=2.2 Hz). LC-MS APCI: m/z 531.0 [M+H]+.
