In a microwave vial (6-bromo-pyridin-2-yl)-hydroxy-acetic acid methyl ester (430.9 mg, 1.75 mmol), 3-(2-methoxy-phenyl)-5-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-1-(toluene-4-sulfonyl)-1H-pyrrolo[2,3-b]pyridine (1.00 g, 1.75 mmol) in tetrahydrofuran/acetonitrile/1 N aqueous sodium bicarbonate (20 ml) was degassed with nitrogen and 1,1′-bis(diphenylphosphino)ferrocenepalladium(II)-dichloride dichloromethane adduct (143.0 mg, 0.18 mmol) was added and the vial sealed. This reaction mixture was heated to 80° C. for 30 minutes in a microwave reactor. 100 ml water was added and this mixture was extracted with ethyl acetate (3×) the combined organic layers were dried over magnesium sulfate and purified by silica gel chromatography to yield hydroxy-{6-[3-(2-methoxy-phenyl)-1-(toluene-4-sulfonyl)-1H-pyrrolo[2,3-b]pyridin-5-yl]-pyridin-2-yl}-acetic acid methyl ester as a white solid (312 mg, 32% yield). MS: m/z 544.5 (M+H+).
