A vial was charged with 1-chloro-N-(4-methoxybenzyl)-N-(pyrimidin-4-yl)isoquinoline-6-sulfonamide (INTERMEDIATE ZZZZ; 100 mg, 0.227 mmol), (5-chloro-2-methoxyphenyl)boronic acid (63.4 mg, 0.340 mmol), potassium carbonate (94 mg, 0.680 mmol), and pd(ph3p)4 (26.2 mg, 0.023 mmol). The vial was flushed with Ar (g), then 1,4-dioxane (851 μl) and water (284 μl) were added. The vial was sealed and heated to 100° C. for 30 min in a Biotage Initiator microwave reactor. The mixture was extracted with EtOAc (3×), and the combined organic extracts were concentrated. The residue was purified by chromatography on silica gel (40-g Redi-Sep Gold column, 0-40% EtOAc/Heptane, then 70% EtOAc/Heptane) to give 1-(5-chloro-2-methoxyphenyl)-N-(4-methoxybenzyl)-N-(pyrimidin-4-yl)isoquinoline-6-sulfonamide (91.2 mg, 0.167 mmol, 73.5% yield) as an off-white foam. m/z (ESI) 547.2 (M+H)+.
