A vial was charged with tert-butyl 3-bromo-6-(N-(2,4-dimethoxybenzyl)-N-(1,2,4-thiadiazol-5-yl)sulfamoyl)-1H-pyrrolo[2,3-b]pyridine-1-carboxylate (531.8 mg, 0.871 mmol), (2-(1-methyl-1H-pyrazol-5-yl)-4-(trifluoromethyl)phenyl)boronic acid (306 mg, 1.132 mmol), potassium phosphate (555 mg, 2.61 mmol), and Pd(AmPhos)2Cl2 (30.8 mg, 0.044 mmol). 1,4-Dioxane (2178 μl) and water (726 μl) were added in sequence. The vial was sealed and heated in a microwave reactor for 30 min at 90° C. The organic layer was removed via pipette, and the aq. layer was extracted with EtOAc (2×). The combined organic extracts were concentrated in vacuo. The crude product was purified by chromatography on silica gel (0 to 50% EtOAc/Heptane) to give tert-butyl 6-(N-(2,4-dimethoxybenzyl)-N-(1,2,4-thiadiazol-5-yl)sulfamoyl)-3-(2-(1-methyl-1H-pyrazol-5-yl)-4-(trifluoromethyl)phenyl)-1H-pyrrolo[2,3-b]pyridine-1-carboxylate (469 mg, 0.621 mmol, 71.2% yield) as a white solid. m/z (ESI) 756.2 (M+H)+.
