Versuchsvorschrift

To a mixture of toluene-4-sulfonic acid 1-(1-benzenesulfonyl-5-fluoro-1H-pyrrolo[2,3-b]pyridin-2-yl)-2-cyclopentyl-vinyl ester (600 mg, 1.1 mmol), 4-(2-methoxy-ethanesulfonyl)-phenylboronic acid (678 mg, 2.8 mmol) and dichlorobis(triphenylphosphine)palladium (II) (77 mg, 0.1 mmol) in dioxane (6 mL) was added an aqueous sodium carbonate solution (2 M, 1.4 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, 25% ethyl acetate/hexanes) afforded 1-benzenesulfonyl-2-{2-cyclopentyl-1-[4-(2-methoxy-ethanesulfonyl)-phenyl]-vinyl}-5-fluoro-1H-pyrrolo[2,3-b]pyridine (400 mg, 63%) as a white solid: LC/MS m/e calcd for C29H29FN2O5S2 [M+H]+ 569.69, observed 569.1.
