実験手順

To a mixture of toluene-4-sulfonic acid 1-(1-benzenesulfonyl-5-fluoro-1H-pyrrolo[2,3-b]pyridin-2-yl)-3-methyl-but-1-enyl ester (prepared as in Example 99, 3.09 g, 6 mmol), 2-fluoro-4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-benzoic acid methyl ester (prepared as in Example 95, 5.88 g, 21 mmol) and dichlorobis(triphenylphosphine)palladium (II) (420 mg, 0.6 mmol) in dioxane (24 mL) was added an aqueous sodium carbonate solution (2 M, 7.5 mL). The resulting mixture was subjected to microwave irradiation for 4 h at 100° C. The mixture was diluted with ethyl acetate (200 mL), washed with a saturated aqueous sodium bicarbonate solution (3×50 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)-3-methyl-but-1-enyl]-2-fluoro-benzoic acid methyl ester (2.50 g, 83%) as a white solid: LC/MS m/e calcd for C26H22F2N2O4S [M+H]+ 497.54, observed 496.7.
