Reaction Steps
(E)-3-[1-(4-Bromo-benzenesulfonyl)-1H-pyrrol-3-yl]-N-(tetrahydro-pyran-2-yloxy)-acrylamide (966 mg) and 1-methyl-4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-1H-pyrazole (662 mg) are dissolved in DME (35 mL) and (Ph3P)3PdCl2 (298 mg) and 2M Na2CO3-solution (3.2 mL) are added. The mixture is heated 16 h to reflux temperature. The mixture is filtered and evaporated and the crude product is purified by silica gel flash chromatography.
