実験手順

To a mixture of 1-benzenesulfonyl-2-[2-cyclopentyl-1-(toluene-4-sulfonyloxy)-vinyl]-1H-pyrrolo[2,3-b]pyridin-5-carboxylic acid methyl ester (prepared as in Example 3, 0.90 g, 1.55 mmol), 2-(methylsulfanyl)pyridine-5-boronic acid hydrate (0.52 g, 3.1 mmol) and dichlorobis(triphenylphosphine)palladium (II) (108 mg, 0.15 mmol) in dioxane (6 mL) was added an aqueous sodium carbonate solution (2 M, 3.1 mL). The resulting mixture was subjected to microwave irradiation for 60 min at 100° C. The mixture was diluted with ethyl acetate (150 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, 25% ethyl acetate/hexanes) afforded 1-benzenesulfonyl-2-[2-cyclopentyl-1-(6-methylsulfanyl-pyridin-3-yl)-vinyl]-1H-pyrrolo[2,3-b]pyridin-5-carboxylic acid methyl ester (300 mg, 36%) as a white solid: LC/MS m/e calcd for C28H27N3O4S2 [M+H]+ 534.67, observed 534.1.
