Into a 500 mL round bottomed flask were added 5-Bromo-3-iodo-1-(toluene-4-sulfonyl)-1H-pyrrolo[2,3-b]pyridine (11.80 g, 20.96 mmol), 2-methoxyphenyl boronic acid (3.76 g, 24.74 mmol), dichlorobis(triphenylphosphine)palladium(II) (0.756 g, 1.08 mmol), acetonitrile (100 mL) and 100 mL of 2M Na2CO3 (aq). The flask was fitted with a reflux condenser and heated at 60° C. with rapid stirring under for 8 h. The reaction mixture was filtered to obtain a grey-tan precipitate, which was dissolved in EtOAc and washed with water followed by brine. Concentration of this solution afforded 7.70 g (80%) of the title compound as a tan powder. 1H-NMR (500 MHz, d6-DMSO) δ 8.50 (d, J=2.0 Hz 1H), 8.14 (d, J=2.5 Hz, 1H), 8.07 (s, 1H), 8.03 (d, J=8.0 Hz, 2H), 7.54 (dd, J=1.5, 7.5 Hz, 1H), 7.43 (d, J=8.0 Hz, 2H), 7.39 (m, 1H), 7.15 (d, J=7.5 Hz, 1H), 7.05 (t, J=7.0 Hz, 1H), 3.80 (s, 3H), 2.34 (8, 3H): MS: m/z 456.9/458.9 [MH+].
