Procedure

To a mixture of toluene-4-sulfonic acid 1-[1-benzenesulfonyl-5-(2,2-dimethyl-[1,3]dioxolan-4-yl)-1H-pyrrolo[2,3-b]pyridin-2-yl]-2-cyclopentyl-vinyl ester (1.7 g, 2.7 mmol), bis(triphenylphosphine)palladium(II) chloride (190 mg, 0.27 mmol) and 4-(methanesulfonyl)phenylboronic acid (1.1 g, 5.5 mmol) in dioxane (10 mL) was added a 2M sodium carbonate solution (3.4 mL) at 25° C. The mixture was subjected to microwave irradiation for 1.5 h at 100° C. The mixture was cooled to 25° C., extracted with ethyl acetate, washed with brine and dried over anhydrous sodium sulfate. Purification by flash silica gel chromatography (silica gel from QingDao, 200-300 mesh, glass column from Shanghai SD company, 30% ethyl acetate/hexanes) afforded 1-benzenesulfonyl-2-[2-cyclopentyl-1-(4-methanesulfonyl-phenyl)-vinyl]-5-(2,2-dimethyl-[1,3]dioxolan-4-yl)-1H-pyrrolo[2,3-b]pyridine (1.1 g, 67.2%) as a yellow solid: LC/MS m/e calcd for C32H35N2S2O6 [M+H]+ 607.77, observed 607.3; 1H NMR (400 MHz, CDCl3) δ ppm 1.47-1.62 (m, 4H), 1.52 (s, 3H), 1.60 (s, 3H), 1.71-1.98 (m, 4H), 2.68 (m, 1H), 3.07 (s, 3H), 3.80 (m, 1H), 4.40 (dd, J=6.3 Hz, 8.3 Hz, 1H), 5.22 (m, 1H), 6.35 (d, J=10.1 Hz, 1H), 6.58 (s, 1H), 7.29 (m, 2H), 7.37, 7.39 (2d, J=8.6 Hz, 2H), 7.49 (t, J=7.5 Hz, 1H), 7.74 (m, 2H), 7.78, 7.79 (2d, J=8.6 Hz, 2H), 7.96, 7.97 (2d, J=2.1 Hz, 1H), 8.50, 8.51 (2d, J=2.1 Hz, 1H).
