실험 절차

To a mixture of toluene-4-sulfonic acid-1-(1-benzenesulfonyl-1H-pyrrolo[2,3-b]pyridin-2-yl)-2-cyclopentyl-vinyl ester (prepared as in Example 43, 0.15 g, 0.28 mmol), 1,4-benzodioxane-6-boronic acid (0.13 g, 0.72 mmol) and dichlorobis(triphenylphosphine)palladium (II) (21 mg, 0.03 mmol) in dioxane (3 mL) was added an aqueous sodium carbonate solution (2 M, 0.36 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 (2×30 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-[2-cyclopentyl-1-(2,3-dihydro-benzo[1,4]dioxin-6-yl)-vinyl]-1H-pyrrolo[2,3-b]pyridine (130 mg, 96%) as a white solid: LC/MS m/e calcd for C28H26N2O4S [M+H]+ 487.59, observed 487.2.
