Procedure

To a solution of N-(7-(6-chloro-5-fluoro-4-methylpyridin-3-yl)isoquinolin-3-yl)cyclopropanecarboxamide (180.0 mg, 0.5059 mmol) in ethanol (10 mL, 200 mmol) was added sodium bicarbonate (95.2 mg, 1.13 mmol) and palladium (60.1 mg, 0.0565 mmol) (10 wt % on carbon). The reaction vessel was purged first with nitrogen and then hydrogen, and then stirred under a hydrogen balloon at 40° C. for 12 hours. The reaction mixture was then filtered through celite and evaporated in vacuo. The crude product was purified via reverse phase HPLC and lyophilized to yield 77.3 mg (48%) of N-(7-(5-fluoro-4-methylpyridin-3-yl)isoquinolin-3-yl)cyclopropanecarboxamide. LCMS (ESI): RT (min)=4.130, M+H=322.1, method=E; 1H NMR (400 MHz, DMSO-d6) δ 10.95 (s, 1H), 9.20 (s, 1H), 8.55 (s, 1H), 8.52 (s, 1H), 8.42 (s, 1H), 8.12 (s, 1H), 7.98 (d, J=8.5 Hz, 1H), 7.76 (dd, J=8.5, 1.4 Hz, 1H), 2.26 (d, J=1.8 Hz, 3H), 2.15-2.03 (m, 1H), 0.94-0.75 (m, 4H).
