実験手順

To a mixture of 1-benzenesulfonyl-2-[3-methyl-1-(toluene-4-sulfonyloxy)-but-1-enyl]-1H-pyrrolo[2,3-b]pyridin-5-carboxylic acid methyl ester (1.2 g, 2.1 mmol), 4-(methanesulfonyl)phenylboronic acid (1.0 g, 5.2 mmol), dichlorobis(triphenylphosphine)palladium (II) (150 mg, 0.21 mmol) in dioxane (10 mL) was added an aqueous sodium carbonate solution (2 M, 5.2 mL). The resulting mixture was subjected to microwave irradiation for 120 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 column chromatography (QingDao silica gel, 200-300 mesh, 50% ethyl acetate/hexanes) afforded 1-benzenesulfonyl-2-[1-(4-methanesulfonyl-phenyl)-3-methyl-but-1-enyl]-1H-pyrrolo[2,3-b]pyridin-5-carboxylic acid methyl ester (820 mg, 73%) as a light yellow solid: LC/MS m/e calcd for C27H26N2O6S2 [M+H]+ 539.65, observed 539.3; 1H NMR (400 MHz, CDCl3) δ ppm 1.16 (d, J=6.6 Hz, 3H), 1.18 (d, J=6.6 Hz, 3H), 2.68 (m, 1H), 3.08 (s, 3H), 3.99 (s, 3H), 6.27 (d, J=10.2 Hz, 1H), 6.67 (s, 1H), 7.28 (m, 2H), 7.36 (m, 2H), 7.49 (m, 1H), 7.67 (m, 2H), 7.78 (m, 2H), 8.55 (d, J=2.0 Hz, 1H), 9.14 (d, J=2.0 Hz, 1H).
