To a solution of N-{2-bromo-6-methyl-3-[3-(methyloxy)phenyl]thieno[2,3-b]pyridin-4-yl}-3-chlorobenzenesulfonamide (Example 33) (100 mg, 0.191 mmol) in 1,4-dioxane (2 mL) was added 3-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (59.6 mg, 0.286 mmol), bis(triphenylphosphine)palladium(II) chloride (13.40 mg, 0.019 mmol) and potassium carbonate (79 mg, 0.573 mmol). Water (1 mL) was added and the mixture heated at 100° C. in a microwave for 15 min (×2). The solvent was removed in vacuo and the residue dissolved in ethyl acetate (20 mL) and washed with water (20 mL). The aqueous phase re-extracted with ethyl acetate (2×20 mL). All organic phases were combined, dried over MgSO4, filtered and concentrated. The residue was purified on silica, eluting with a gradient of 0-80% ethyl acetate in cyclohexane and then further purified using MDAP (acidic conditions), to give the title compound (15 mg). LCMS (A) m/z: 525 [M+1]+, Rt 1.23 min (acidic).
