반응 단계
9-Borabicyclo[3.3.1]nonane (540 mg) was added to THF solution (5 mL) of 4-fluorostyrene (240 mL) and stirred at room temperature for 2 hours. To the reaction liquid, the compound synthesized in Step (1) of Example 45(340 mg), tetrakis(triphenylphosphine)palladium (60 mg), DMF (5 mL) and 2M aqueous sodium carbonate solution (1 mL) were added and stirred at 100° C. for 19 hours. Saturated brine was added to the reaction liquid, followed by extraction with ethyl acetate and drying over anhydrous magnesium sulfate. Concentrating the solvent under reduced pressure, the residue was purified on silica gel column chromatography (C-200; ethyl acetate:hexane=1:9-1:4) to provide the title compound (336 mg, 100%).
