To a solution of 2-[(6-chloropyridazin-3-yl)amino]-5-[2,6-difluoro-4-(1-hydroxy-1-methylethyl)phenyl]thiophene-3-carboxamide (64 mg, 0.15 mmol) in THF (3 ml), was added 1H-pyrazol-3-yl boronic acid (34 mg, 0.30 mmol), and sodium bicarbonate (0.38 ml, 0.75 mmol, 2 M). Palladium tetrakis triphenylphosphine (35 mg, 0.03 mmol) was added last and the vial was purged with nitrogen for 5 minutes. The crude product was washed with 3:1 chloroform:isopropanol and water. The resulting organic layer was dried over magnesium sulfate and concentrated under reduced pressure. Purification by column chromatography yielded the title compound.
