Procedure
A round-bottom flask was charged with perfluorophenyl 1-chloroisoquinoline-6-sulfonate (see EXAMPLE 73, Step 1; 555 mg, 1.355 mmol), 2-chloro-4-methoxy-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzonitrile (INTERMEDIATE UUUU, 477 mg, 1.626 mmol), potassium carbonate (562 mg, 4.06 mmol), and Pd(Ph3P)4 (157 mg, 0.135 mmol). The vial was flushed with Ar (g), then 1,4-dioxane (5080 μl) and water (1693 μl) were added. The flask was lowered into a 50° C. heating bath for 1 h. The reaction mixture was diluted with water and EtOAc. The organic extract was dried over sodium sulfate, filtered, and concentrated. The residue was purified by chromatography on silica gel (40-g Redi-Sep Gold column, 0-50% EtOAc/Heptane) to give perfluorophenyl 1-(4-chloro-5-cyano-2-methoxyphenyl)isoquinoline-6-sulfonate (583.89 mg, 1.080 mmol, 80% yield) as an off-white foam. m/z (ESI) 540.9 (M+H)+.
