Reaction Steps

N-(7-bromoisoquinolin-3-yl)cyclopropanecarboxamide (150 mg, 0.595 mmol), 5-chloro-2-methoxyphenylboronic acid (132 mg, 0.714 mmol), [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II) (24 mg, 0.03 mmol) and cesium carbonate (232 mg, 0.714 mmol) were mixed in acetonitrile and water (10:1, 20 mL). The reaction mixture was stirred at 120° C. under nitrogen for 6 hours. The reaction mixture was concentrated, diluted with water and extracted with ethyl acetate, concentrated and purified by prep-HPLC to give the desired product (21.3 mg, 10.2%). LCMS (ESI): RT (min)=1.216, M+H+=352.9, Method=I; 1H NMR (400 MHz, DMSO-d6) δ 10.93 (s, 1H), 9.14 (s, 1H), 8.46 (s, 1H), 8.12 (s, 1H), 7.84-7.42 (m, 4H), 7.18 (d, J=8.4 Hz, 1H), 3.78 (s, 3H), 2.09-2.05 (m, 1H), 0.88-0.83 (m, 4H).
