Reaction Steps

A mixture of N-(7-(2-chloro-5-fluoropyridin-3-yl)isoquinolin-3-yl)cyclopropanecarboxamide (105.4 mg, 0.3084 mmol), trimethylboroxine (129.0 uL, 0.9228 mmol), bis(di-tert-butyl(4-dimethylaminophenyl)phosphine)dichloropalladium(II) (22.3 mg, 0.0315 mmol), and potassium carbonate (112.5 mg, 0.8140 mmol) in 1,4-dioxane (2.0 mL, 26 mmol) was heated at 90° C. for 26 hours. The reaction mixture was then diluted with dichloromethane, washed with water, dried over MgSO4, filtered, and evaporated in vacuo. The crude product was purified via reverse phase HPLC and lyophilized to yield 50.6 mg (51%) of N-(7-(5-fluoro-2-methylpyridin-3-yl)isoquinolin-3-yl)cyclopropanecarboxamide. LCMS (ESI): RT (min)=3.972, M+H=322.0, method=E; 1H NMR (400 MHz, DMSO-d6) δ 10.96 (s, 1H), 9.19 (s, 1H), 8.52 (s, 2H), 8.12 (s, 1H), 7.97 (d, J=8.6 Hz, 1H), 7.86-7.67 (m, 2H), 2.47 (s, 3H), 2.08 (dd, J=12.4, 7.3 Hz, 1H), 0.86 (dd, J=9.3, 6.4 Hz, 4H).
