Versuchsvorschrift

A mixture of methyl 7-bromo-1-(4-sulfamoylphenyl)-2,3-dihydro-1H-1-benzazepine-4-carboxylate (0.31 g), 4-(2-butoxyethoxy)phenyl borate (0.22 g), 1M potassium carbonate solution (3 ml), ethanol (5 ml) and toluene (50 ml) was stirred under argon atmosphere at room temperature for 30 minutes. To the mixture was added tetrakis(triphenylphosphine)palladium (0.04 g), and the mixture was refluxed under argon atmosphere for 3 hours and extracted with ethyl acetate. The organic layer was washed with water and saturated brine and dried with anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure and the residue was purified with silica gel column chromatography (ethyl acetate/hexane) to give methyl 7-[4-(2-butoxyethoxy)phenyl]-1-(4-sulfamoylphenyl)-2,3-dihydro-1H-1-benzazepine-4-carboxylate (0.34 g) as yellow crystals.
