Versuchsvorschrift

A microwave vial was charged with 1-chloro-N-(2,4-dimethoxybenzyl)-N-(thiazol-2-yl)isoquinoline-6-sulfonamide (0.075 g, 0.158 mmol), (2-bromo-4-(trifluoromethyl)phenyl)boronic acid (0.064 g, 0.236 mmol), tetrakis(triphenylphosphine)palladium(0) (0.018 g, 0.016 mmol), and potassium carbonate (0.109 g, 0.788 mmol). Dioxane (1.182 ml) and water (0.394 ml) were added, the vial was flushed with argon and sealed, and microwaved at 100° C. for 30 minutes. 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 by silica gel chromatography (12 g column, gradient elution 0 to 50% EtOAc:Heptane) to afford 1-(2-bromo-4-(trifluoromethyl)phenyl)-N-(2,4-dimethoxybenzyl)-N-(thiazol-2-yl)isoquinoline-6-sulfonamide as a white solid. m/z (ESI) 664.1 (M+H)+.
