Reaction Steps
Under nitrogen, N-(3-bromo-2,6-dimethylthieno[2,3-b]pyridin-4-yl)-3-chlorobenzenesulfonamide (Example 61) (65 mg, 0.151 mmol) was dissolved in 1,4-dioxane (1.5 mL) and water (0.7 mL). 3-(Methyloxy)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine (53.1 mg, 0.226 mmol), tetrakis(triphenylphosphine)palladium(0) (17.40 mg, 0.015 mmol) and potassium carbonate (62.4 mg, 0.452 mmol) were added and the mixture heated in a microwave at 120° C. for 10 min. Ethyl acetate (10 mL) was then added and the mixture washed with water (2×5 mL). The organic layer was dried over MgSO4, filtered and the solvent removed in vacuo. The residue was purified by normal phase chromatography, eluting with a gradient of 0-5% MeOH in DCM, and then further purified by MDAP (acidic conditions), to give the title compound (17.2 mg). LCMS (A) m/z: 460 [M+1]+, Rt 0.90 min (acidic).
