Reaction Conditions

Reaction Steps

Under a nitrogen atmosphere, 4-trifluoromethane-sulfonyloxyanisole (0.49 g, 1.9 mmol), phenylboronic acid (0.29 g, 2.4 mmol), potassium fluoride (0.24 g, 4.2 mmol), (π-allyl)palladium chloride (3.6 mg, 0.01 mmol), 2,2-diphenyl-1-(di-tert-butylphosphino)-1-methylcyclopropane (14.0 mg, 0.04 mmol) obtained in Example 4 and toluene (4 ml) were placed in a reaction flask and stirred for 1.5 hours at 80° C. The reaction mixture was cooled, washed with water, and dried over anhydrous magnesium sulfate. Then, the solvent was removed under reduced pressure, and the concentrate was purified by column chromatography to give the title compound (0.34 g, 96%) as white crystal.
