Procedure

To a mixture of toluene-4-sulfonic acid-1-(1-benzenesulfonyl-5-methoxy-1H-pyrrolo[2,3-b]pyridin-2-yl)-2-(tetrahydro-pyran-4-yl)-vinyl ester (1.1 g, 1.94 mmol), 4-(methanesulfonyl)phenylboronic acid (775 mg, 3.88 mmol), dichlorobis(triphenylphosphine)palladium (II) (136 mg, 0.194 mmol) in dioxane (5 mL) was added an aqueous sodium carbonate solution (2 M, 2.5 mL, 5 mmol). The resulting mixture was subjected to microwave irradiation for 2 h at 100° C. The resulting mixture was diluted with ethyl acetate (250 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-2-[1-(4-methanesulfonyl-phenyl)-2-(tetrahydro-pyran-4-yl)-vinyl]-5-methoxy-1H-pyrrolo[2,3-b]pyridine (540 mg, 54%) as a light yellow solid: LC/MS m/e calcd for C28H28N2O6S2 [M+H]+ 553.67, observed 553.2.
