실험 절차

To a mixture of toluene-4-sulfonic acid 1-(1-benzenesulfonyl-5-tert-butoxycarbonylamino-1H-pyrrolo[2,3-b]pyridin-2-yl)-2-cyclopentyl-vinyl ester (0.5 g, 0.78 mmol), 4-methylsulfonyl phenylboronic acid (468 mg, 2.34 mmol), dichlorobis(triphenylphosphine)palladium (II) (55 mg, 0.08 mmol) in dioxane (5 mL) was added an aqueous sodium carbonate solution (2 M, 1.17 mL, 2.34 mmol). The resulting mixture was subjected to microwave irradiation for 3 h at 100° C. The mixture was diluted with ethyl acetate (80 mL), washed with a saturated aqueous sodium bicarbonate solution (2×20 mL), brine, dried over anhydrous sodium sulfate and then concentrated in vacuo. Purification by flash column chromatography (QingDao silica gel, 200-300 mesh, 33% ethyl acetate/hexanes) afforded {1-benzenesulfonyl-2-[2-cyclopentyl-1-(4-methanesulfonyl-phenyl)-vinyl]-1H-pyrrolo[2,3-b]pyridin-5-yl}-carbamic acid tert-butyl ester (326 mg, 67%) as a light yellow solid: LC/MS m/e calcd for C32H35N3O6S2 [M+H]+ 622.78, observed 622.1.
