Procedure
5-Bromo-3-iodo-1-(toluene-4-sulfonyl)-1H-pyrrolo[2,3-b]pyridine (Intermediate BZ, 483 mg, 1.01 mmol), 4-aminocarbonylphenylboronic acid (196 mg, 1.22 mmol) and dichlorobis(triphenylphosphine)palladium (II) (71 mg, 0.1 mmol) were combined in CH3CN (10 ml) and 1 M Na2CO3 (10 ml) and stirred at 60° C. for 3 hrs. Water was added and the mixture was extracted with DCM and purified by silica gel chromatography using 0-30% EtOAc/Hexanes. The title compound was obtained in 79% yield (373 mg). 1H NMR (CDCl3, 300 MHz): δ 8.51 (d, J=1.2 Hz, 1H), 8.20 (d, J=1.2 Hz, 1H), 8.11 (d, J=5.1 Hz, 2H), 7.96 (s, 1H), 7.93 (d, J=5.0 Hz, 2H), 7.64 (d, J=5.1 Hz, 2H), 7.31 (d, J=4.8 Hz, 2H), 6.1 (bs, 1H), 5.7 (bs, 1H), 2.39 (s, 3H).
