Procedure

4-Bromo-1-(phenylsulfonyl)-1H-pyrrolo[2,3-b]pyridine (1.546 g), 1-(phenylsulfonyl)-6-(trimethylstannanyl)-1H-indazol-4-amine (2 g) and Pd(PPh3)4 (0.265 g) were added to DMF (30 ml) under nitrogen. The mixture was heated at 100° C. for 2 days then cooled to RT and concentrated in vacuo. The mixture was purified by column chromatography on silica (70 g) eluting with ammonia and methanol in DCM, then again using the ISCO Companion, eluting with a gradient of 30-85% MeCN (+0.1% TFA): H2O (0.1% TFA). Fractions containing desired product were combined and the solvent was removed to afford the title compound as a brown solid (663 mg).
