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 (1 g, 2 mmol), 4-(methanesulfonyl)phenylboronic acid (1 g, 5 mmol) and dichlorobis(triphenylphosphine)palladium (II) (140 mg, 0.2 mmol) in dioxane (8 mL) was added an aqueous sodium carbonate solution (2 M, 2.5 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 (2×50 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, 50% ethyl acetate/hexanes) afforded 1-benzenesulfonyl-5-fluoro-2-[1-(4-methanesulfonyl-phenyl)-3-methyl-but-1-enyl]-1H-pyrrolo[2,3-b]pyridine (0.9 g, 92%) as a white solid: LC/MS m/e calcd for C25H23FN2O4S2 [M+H]+ 499.60, observed 498.8.
