A microwave vial was charged with 1-(2-bromo-4-(trifluoromethyl)phenyl)-N-(4-methoxybenzyl)-N-(1,2,4-thiadiazol-5-yl)isoquinoline-6-sulfonamide (100 mg, 0.157 mmol), potassium carbonate (109 mg, 0.787 mmol), 4-pyridineboronic acid (77 mg, 0.629 mmol), tetrakis(triphenylphosphine)palladium(0) (18.18 mg, 0.016 mmol), dioxane (1049 μl) and water (525 μl). The vial was purged with argon, sealed and heated in a microwave at 100° C. for 35 min. The reaction was cooled to room temperature, diluted with 60 mL of EtOAc, dried over MgSO4, filtered and concentrated. The material was absorbed onto a plug of silica gel and purified by chromatography through a silica gel column (40 g), eluting with a gradient of 0% to 100% (90:10 MeOH:DCM) in DCM, to provide a yellow glass, N-(4-methoxybenzyl)-1-(2-(pyridin-4-yl)-4-(trifluoromethyl)phenyl)-N-(1,2,4-thiadiazol-5-yl)isoquinoline-6-sulfonamide (100 mg, 0.158 mmol). This material was carried on to the next step. MS (ESI): 634.0 [M+H]+.
