To a solution of 1-chloro-N-(4-methoxybenzyl)-N-(thiazol-4-yl)isoquinoline-6-sulfonamide (0.10 g, 0.224 mmol), (2-methoxy-4-(trifluoromethyl)phenyl)boronic acid (0.064 g, 0.292 mmol) and cesium carbonate (0.292 g, 0.897 mmol) in DME (2.437 ml) and Water (0.366 ml) was added Pd(PPh3)4 (0.026 g, 0.022 mmol) in one portion. The resulting mixture was heated to 125° C. in the microwave for 2 hours. The resulting mixture was transferred to a seperatory funnel and the aqueous layer was washed 3× with EtOAc. The organic layers were combined, dried with MgSO4, filtered and concentrated to an oil. The crude mixture was purified by the silica gel chromatography (100% hexanes to 25% EtOAc in hexanes to 90% EtOAc in heptanes). m/z (ESI) 586.2 (M+H)+.
