Procedure

To 1-[3-(5-bromo-1H-pyrrolo[2,3-b]pyridine-3-carbonyl)-4-fluoro-phenyl]-3-butyl-urea (P-1637, 14.0 mg, 0.0000323 mol), 3-pyridylboronic acid (5.96 mg, 0.0000485 mol), and Tetrakis(triphenylphosphine)palladium(0) (0.820 mg, 7.09E-7 mol) were mixed in 1.00 M potassium carbonate in water (1.00 mL) and acetonitrile (2.00 mL, 0.0383 mol). The resulting mixture was heated at 120° C. in the microwave for 40 minutes. The reaction was extracted with ethyl acetate and water twice, and the combined organic layers were washed with 1M sodium bicarbonate followed by brine and the organic layer was dried over magnesium sulfate and filtered. The organic layer was concentrated and purified by reverse phase HPLC (acetonitrile and water with 0.1% formic acid) to give the compound as a white solid (P-1637, 8.5 mg, 61%). MS (ESI) [M+H+]+=432.3.
