Versuchsvorschrift

(E)-3-[1-(4-Bromo-benzenesulfonyl)-1H-pyrrol-3-yl]-N-(tetrahydro-pyran-2-yloxy)-acrylamide (6.8 g) and 1-methyl-4-[4-(4,4,5,5-tetramethyl-[1,3,2]-dioxaborolan-2-yl)-pyridin-2-yl]-piperazine (5.0 g) are dissolved in DME (300 mL). Under an inert gas atmosphere are added (Ph3P)3PdCl2 (2.1 g) and 2M Na2CO3-solution (44 mL). The mixture is heated to 100° C. for 2.5 h. After filtration and extraction, the crude product from the organic phase is purified by silica gel flash chromatography. By means of chloroform/EtOH (30:1-19:1). 5.3 g of the title compound are obtained as brownish oil.
