5-Bromo-1-[(4-methylphenyl)sulfonyl]-1H-pyrazolo[3,4-b]pyridine (605 mg) in DMF (4 ml) was added to a solution of 3-fluoro-1-(phenylsulfonyl)-6-(trimethylstannanyl)-1H-indazol-4-amine (650 mg) in DMF (6 ml), treated with Pd( )Ph3)4 (165 mg) and then heated at 120° C. for 21 h. The solution was allowed to cool, filtered, and then evaporated. The residue was dissolved in chloroform, loaded onto a 100 g silica cartridge which was eluted with 0-100% ethyl acetate:cyclohexane over 60 min using the Flashmaster II. Appropriate peaks were combined and evaporated to give the title compound as a white solid, 0.577 g.
