実験手順
To a stirred solution of 2-[1-(4-bromo-2-fluoro-phenyl)-1-methyl-ethoxy]-tetrahydro-pyran (9.7 g, 30.6 mmol), potassium acetate (9 g, 91.8 mmol) and bis(pinacolato)diboron (9.7 g, 38.2 mmol) in dimethylsulfoxide (65 mL) was added 1,1-bis(diphenylphosphino)ferrocenedichloropalladium(II) (2.5 g, 3.06 mmol) at room temperature. The mixture was heated at 80° C. and stirred for 3 h and then cooled to room temperature and then 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, 9 g, 15.52 mmol) and an aqueous sodium carbonate solution (2 M, 17.85 mL) were added. The mixture was heated at 100° C. and stirred for 3 h. The resulting mixture was cooled to room temperature, extracted with ethyl acetate, washed with brine, dried over anhydrous sodium sulfate. The solvent was evaporated in vacuo and the residue was purified by flash column chromatography (QingDao silica gel, 200-300 mesh, 20% ethyl acetate/hexanes) to afford 1-benzenesulfonyl-2-(2-cyclopentyl-1-{3-fluoro-4-[1-methyl-1-(tetrahydro-pyran-2-yloxy)-ethyl]-phenyl}-vinyl)-1H-pyrrolo[2,3-b]pyridin-5-carboxylic acid methyl ester (6 g, 60%) as a light yellow oil: LC/MS m/e calcd for C36H39FN2O6S [M+H]+ 647.78, observed 647.0.
