Procedure

To propane-1-sulfonic acid [3-(5-bromo-1H-pyrrolo[2,3-b]pyridine-3-carbonyl)-2,4-difluoro-phenyl]-amide (P-0773, prepared as described in Example 1, 65.0 mg, 0.14 mmol) in acetonitrile (4.0 mL) was added pyridine-3-boronic acid (609, 25.0 mg, 0.20 mmol), tetrakis (triphenylphosphine)palladium(0) (11 mg, 1.0% mmol) and aqueous potassium carbonate (1.0 M, 2.0 mL). The reaction was heated to 160° C. for 10 minutes in a CEM Discover microwave instrument. The reaction was poured into water, and extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous sodium sulfate, filtrated and concentrated. The desired compound was isolated by silica gel column chromatography (methylene chloride/methanol 5%) to give a white solid (P-0088, 30 mg, 46.9%). MS(ESI) [M+H+]+=457.2.
