Alternatively, a mixture of N-{2-bromo-6-methyl-3-[3-(methyloxy)phenyl]thieno[2,3-b]pyridin-4-yl}-3-chlorobenzenesulfonamide (310 mg, 0.592 mmol) (Example 33), potassium ferrocyanide (50.0 mg, 0.118 mmol), copper(I) iodide (11.27 mg, 0.059 mmol) in 1-methylimidazole (3 mL, 37.6 mmol) was heated at 160° C. for 2 h. Extra potassium ferrocyanide (100 mg, 0.118 mmol) was added and heating continued at 160° C. for 21 h. The mixture was then cooled to RT. Purification by chromatography on silica gel, eluting with a gradient of 0-60% ethyl acetate in cyclohexane, afforded the title compound (208 mg).
