反応手順

1-Bromo-4-[(E)-2-ethoxysulfonylethenyl]benzene (1.0 g, 3.4 mmol) and benzofuran-2-boronic acid (0.61 g, 3.7 mmol) were dissolved in DMF (20 mL). Sodium carbonate (2M, 10 mL) and tetrakis(triphenylphosphine)palladium(0) (200 mg, 0.17 mmol) were added and the resulting mixture was stirred under argon at 90° C. for 12 h. Water was added to the mixture and the resulting precipitate was collected, washed with water and dried to give the product as a sodium salt which was used in the next step without further purification (0.38 g, 35%).
