実験手順: To a microwave vial charged with 1-chloro-N-(4-methoxybenzyl)-N-(thiazol-2-yl)isoquinoline-6-sulfonamide (0.053 g, 0.119 mmol) was added (2-bromo-4-fluorophenyl)boronic acid (Combi-Blocks, San Diego, Calif.) (0.042 g, 0.190 mmol), potassium carbonate (0.082 g, 0.594 mmol), dioxane (0.594 ml) and water (0.198 ml). The mixture was purged with argon prior to the addition of Pd(PPh3)4 (0.014 g, 0.012 mmol). The vessel was sealed and irradiated at 100° C. for 30 mins affording fairly clean conversion to desired product. The organic phase was decanted, the aqueous rinsed with EtOAc and the EtOAc decanted. The combined organics were dried under reduced pressure and purified with a 25 g HP silicycle column ramping EtOAc in heptane (0-45%, then isocratic at 45%) to provide product as an off-white foam 1-(2-bromo-4-fluorophenyl)-N-(4-methoxybenzyl)-N-(thiazol-2-yl)isoquinoline-6-sulfonamide (Intermediate KKK) (54 mg, 0.092 mmol, 78% yield) with minor impurities according to LC/MS and NMR (˜20% impurity). m/z (ESI) 582.2/584.2 (M+H)+. The mixture was purged with argon The vessel was sealed irradiated at 100° C. for 30 mins
