Reaction Steps

To a microwave vial charged with 1-chloro-N-(4-methoxybenzyl)-N-(thiazol-2-yl)isoquinoline-6-sulfonamide (Intermediate JJJ) (100 mg, 0.224 mmol), 2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenol (49 mg, 0.224 mmol), potassium carbonate (155 mg, 1.121 mmol) and Pd(Ph3P)4 (26 mg, 0.022 mmol) was added Dioxane (1120 μl) and Water (374 μl) and irradiated at 100° C. for 30 min affording conversion to desired product as the primary species. The organic layer was decanted, the aqueous rinsed with EtOAc and the combined organics dried under reduced pressure. The crude material will be used as is for subsequent reactions. m/z (ESI) 504.0 (M+H)+
