실험 절차

To a mixture of toluene-4-sulfonic acid 1-(1-benzenesulfonyl-5-fluoro-1H-pyrrolo[2,3-b]pyridin-2-yl)-2-(tetrahydro-pyran-4-yl)-vinyl ester (prepared as in Example 122, 0.57 g, 1 mmol), 2-fluoro-4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-benzoic acid methyl ester (prepared as in Example 95, 1.2 g, 4.2 mmol) and dichlorobis(triphenylphosphine)palladium (II) (70 mg, 0.1 mmol) in dioxane (8 mL) was added an aqueous sodium carbonate solution (2 M, 1.25 mL). The resulting mixture was subjected to microwave irradiation for 2 h at 100° C. The mixture was diluted with ethyl acetate (100 mL), washed with a saturated aqueous sodium bicarbonate solution (2×30 mL), brine, dried over anhydrous sodium sulfate and then concentrated in vacuo. Purification by flash silica gel chromatography (silica gel from QingDao, 200-300 mesh, glass column from Shanghai SD company, 25% ethyl acetate/hexanes) afforded 4[1-(1-benzenesulfonyl-5-fluoro-1H-pyrrolo[2,3-b]pyridin-2-yl)-2-(tetrahydro-pyran-4-yl)-vinyl]-2-fluoro-benzoic acid methyl ester (400 mg, 72%) as a white solid: LC/MS m/e calcd for C28H24F2N2O5S [M+H]+ 539.57, observed 539.0.
