Versuchsvorschrift

A suspension of 1-(phenylsulfonyl)-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrrolo[2,3-b]pyridine (4.63 g, 12.1 mmol), 2,6-dichloro-4-iodopyridine (3.00 g, 11.0 mmol), dichlorobis(triphenylphosphine)palladium(II) (0.308 g, 0.438 mmol) and sodium carbonate (1M, 8.76 mL, 8.76 mmol) in 1,2-dimethoxyethane/ethanol/water (7:2:3) (30 mL) was degassed and heated at 80° C. overnight. After cooling, the suspension was diluted with ethyl acetate, filtered, washed with ethyl acetate and water, and oven-dried to give 3.98 g (90%) of the title compound.
