실험 절차

A mixture of Example 6a (0.642 g, 1.5 mmol), 2-bromo-1-fluoro-4-(methylsulfonyl)benzene (0.380 g, 1.500 mmol), 1,3,5,7-tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamantane (0.051 g, 0.176 mmol), tris(dibenzylideneacetone)dipalladium(0) (0.041 g, 0.045 mmol), and potassium phosphate (0.796 g, 3.75 mmol) in dioxane (10 mL) and water (2.500 mL) was degassed and back-filled with nitrogen several times. The reaction was heated at 60° C. for 16 hours. The reaction mixture was partitioned between water and ethyl acetate. The aqueous layer was extracted with additional ethyl acetate three times. The combined organic layers were washed with saturated aqueous sodium chloride, dried over anhydrous magnesium sulfate, filtered, and concentrated. The residue was purified by flash column chromatography on silica gel eluting with 30% ethyl acetate in hexanes to give the title compound (0.63 g, 1.328 mmol, 89% yield).
