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 (prepared as in Example 31, 350 mg, 0.62 mmol), 4-(trifluoromethyl)phenylboronic acid (293 mg, 1.54 mmol) and dichlorobis(triphenylphosphine)palladium (II) (43 mg, 0.06 mmol) in dioxane (5 mL) was added an aqueous sodium carbonate solution (2 M, 0.8 mL, 1.6 mmol). The resulting mixture was subjected to microwave irradiation for 2 h at 100° C. The 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-5-methoxy-2-[2-(tetrahydro-pyran-4-yl)-1-(trifluoromethyl-phenyl)-vinyl]-1H-pyrrolo[2,3-b]pyridine (272 mg, 82%) as a light yellow solid: LC/MS m/e calcd for C28H25F3N2O4S [M+H]+ 543.58, observed 543.2.
