実験手順

To a solution of copper chloride (10 mg) and Pd(PPh3)4 (60 mg) in DMF (2 mL) were added [(4-isobutylphenyl)ethynyl](trimethyl)silane (288 mg) and 5-fluoro-3-formyl-2H-chromen-7-yl trifluoromethanesulfonate (340 mg) at room temperature, followed by stirring at 80° C. for 12 hours. The reaction liquid was concentrated and the residue was purified by silica gel column chromatography (CHCl3) to obtain 5-fluoro-7-[(4-isobutylphenyl)ethynyl]-2H-chromene-3-carbaldehyde (83 mg) as a yellow solid.
