Reaction Steps

To solution of N-(2-bromo-3,6-dimethylthieno[2,3-b]pyridin-4-yl)-3-chlorobenzenesulfonamide (Example 77) (100 mg, 0.232 mmol) in 1,4-dioxane (2 mL) and water (1 mL) was added 1-benzofuran-2-ylboronic acid (56.3 mg, 0.347 mmol), bis(triphenylphosphine)palladium(II) chloride (16.26 mg, 0.023 mmol) and potassium carbonate (112 mg, 0.811 mmol) and the reaction mixture heated at 100° C. using a microwave reactor for 30 min. The mixture was then filtered through celite, washing with DCM (20 mL×2) and the filtrate dried (phase separation cartridge) and concentrated. The residue was then purified by MDAP (acidic conditions), followed by MDAP (basic conditions) to afford the title compound (10.89 mg). LCMS (A) m/z: 469 [M+1]+, Rt 1.42 min (acidic).
