Reaction Steps

To a solution of N-(2-bromo-3,6-dimethylthieno[2,3-b]pyridin-4-yl)-3-chlorobenzenesulfonamide (Example 77) (80 mg, 0.185 mmol), 1H-pyrazol-3-ylboronic acid (20.73 mg, 0.185 mmol) and bis(triphenylphosphine)palladium(II) chloride (13.01 mg, 0.019 mmol) in 1,4-dioxane (2 mL) and water (1 mL) was added potassium carbonate (90 mg, 0.649 mmol) and the mixture heated to 100° C. using a microwave reactor for 30 min. The mixture was then evaporated to dryness and purified by MDAP (acidic conditions), followed by MDAP (basic conditions), to afford the title compound (8.07 mg). LCMS (A) m/z: 417 [M−1]−, Rt 0.99 min (acidic).
