실험 절차

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-(1-Pyrrolidinyl)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine (Description 79) (181 mg, 0.66 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, all three mixtures were combined and concentrated. The residue was passed through an SCX cartridge, eluting with MeOH (75 mL) and then 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 and then further purified by MDAP (acidic conditions), to give the title compound (61 mg). LCMS (A) m/z: 551 [M+1]+, Rt 0.79 min (acidic).
