Procedure

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), 4-[5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-3-pyridinyl]morpholine (Description 81) (214 mg, 0.737 mmol), potassium carbonate (71.0 mg, 0.514 mmol), tetrakis(triphenylphosphine)palladium(0) (19.79 mg, 0.017 mmol) and bis(triphenylphosphine)palladium(II) chloride (12.02 mg, 0.017 mmol) were weighed into a microwave vial. 1,4-Dioxane (2 mL), DMF (1 mL) and water (0.5 mL) were added and the mixture heated in a microwave at 120° C. for 15 min. At this point, both mixtures were combined and concentrated. The residue was passed through an SCX cartridge, eluting with MeOH (75 mL) and then with 2M NH3 in MeOH (150 mL). The basic methanolic solution was concentrated and purified by normal phase chromatography, eluting with 0-10% MeOH in DCM, to give the title compound (65 mg). LCMS (A) m/z: 567 [M+1]+, Rt 0.72 min (acidic).
