Versuchsvorschrift

A mixture of 6-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1-tosyl-1H-pyrrolo[2,3-c]pyridin-7(6H)-one (6.00 g, 14.0 mmol), N-(3-bromo-4-(2,4-difluorophenoxy)phenyl)ethanesulfonamide (5.77 g, 14.7 mmol), 1,3,5,7-tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamantane (0.205 g, 0.700 mmol), tris(dibenzylideneacetone)dipalladium(0) (0.321 g, 0.350 mmol) and potassium phosphate (2.97 g, 14.0 mmol) was combined and sparged with argon for 30 minutes. A mixture of dioxane (60 mL) and water (15 mL) was sparged with nitrogen for 30 minutes and transferred by syringe into the reaction vessel under argon. The reaction mixture was stirred at 60° C. for 2 hours, cooled to ambient temperature, and partitioned between ethyl acetate and water. The organic layer was washed with brine, dried (anhydrous sodium sulfate), treated with silica gel (2-4 g) for 45 minutes, filtered and concentrated to afford N-(4-(2,4-difluorophenoxy)-3-(6-methyl-7-oxo-1-tosyl-6,7-dihydro-1H-pyrrolo[2,3-c]pyridin-4-yl)phenyl)ethanesulfonamide (8 g, 13.04 mmol, 93% yield).
