実験手順

1-Benzenesulfonyl-3-bromo-1H-pyrrolo[2,3-b]pyridine (4, 1.00 g, 2.96 mmol) was dissolved in tetrahydrofuran (16 mL) and 3,4-dimethoxyphenyl boronic acid (1.35 g, 7.41 mmol), tetrakis(triphenylphosphine)palladium(0) (200 mg, 0.1 mmol), and 1 M potassium carbonate (8 mL) were added. The reaction mixture was heated in a CEM Discover microwave at 120° C. for 10 minutes. The reaction mixture was concentrated under reduced pressure and partitioned between ethyl acetate and water. The organic portions were dried with anhydrous magnesium sulfate, filtered, and the filtrate was adsorbed onto silica. The mixture was purified by flash chromatography (30% ethyl acetate:hexanes) to provide the desired product, 5, (909 mg, 78%). MS(ESI) [M+H+]+=394.9.
