A microwave vial was charged with 1-(5,6-dichloro-2-methoxypyridin-3-yl)-N-(1,3,4-thiadiazol-2-yl)isoquinoline-6-sulfonamide (0.032 g, 0.068 mmol), (3-fluorophenyl)boronic acid (0.014 g, 0.102 mmol), potassium carbonate (0.028 g, 0.205 mmol), and Pd(Ph3P)4 (7.90 mg, 6.83 μmol). The vial was flushed with Ar (g), then Dioxane (0.512 ml) and Water (0.171 ml) were added. The reaction was microwaved at 90° C. for one hour. The reaction was diluted with ethyl acetate and washed with water. The aqueous layer was extracted with ethyl acetate, and the combined organic layers were dried with sodium sulfate, filtered, and concentrated. The material was purified via column chromatography (RediSep Gold 12 g, gradient elution 0-10% MeOH:DCM) to afford 1-(5-chloro-6-(3-fluorophenyl)-2-methoxypyridin-3-yl)-N-(1,3,4-thiadiazol-2-yl)isoquinoline-6-sulfonamide as a tan solid. 1H NMR (400 MHz, DMSO-d6) δ=8.80 (s, 1H), 8.74 (d, J=5.7 Hz, 1H), 8.60 (s, 1H), 8.19 (d, J=5.9 Hz, 1H), 8.12 (s, 1H), 7.91 (s, 2H), 7.74 (d, J=8.0 Hz, 1H), 7.72-7.67 (m, J=2.2, 9.7 Hz, 1H), 7.61 (dt, J=6.1, 7.9 Hz, 1H), 7.37 (dt, J=2.2, 8.5 Hz, 1H), 3.82 (s, 3H). m/z (ESI) 528.2 (M+H)+.
