A mixture of 1,1-dimethylethyl 4-(3-bromo-4-{[(3-chlorophenyl)sulfonyl]amino}-6-methylthieno[2,3-b]pyridin-2-yl)-1H-pyrazole-1-carboxylate (Description 75) (100 mg, 0.171 mmol), 3-(morpholino)phenylboronic acid, pinacol ester (74.3 mg, 0.257 mmol), potassium carbonate (95 mg, 0.685 mmol) and tetrakis(triphenylphosphine)palladium(0) (3.96 mg, 3.43 μmol) were weighed into a microwave vial. 1,4-Dioxane (1.5 mL), DMF (0.75 mL) and water (0.38 mL) were added and the mixture heated in a microwave at 110° C. for 30 min. At this point, both reaction mixtures were combined and concentrated. Purification by chromatography on silica, eluting with a gradient of 0-100% ethyl acetate in DCM, followed by MDAP (acidic conditions), afforded the title compound (44 mg). LCMS (A) m/z: 566 [M+1]+, Rt 1.24 min (acidic).
