Versuchsvorschrift

3.6 g of the 4-[4-(2-pyridyl)-piperazin-1-yl]butylamine obtained above were added to a reaction mixture cooled to -20° C. which contained, in 100 ml of absolute dichloromethane, a mixed anhydride produced in a manner analogous to Example 1 (a) from 4.0 g flavone-3-carboxylic acid, 3.367 g dimethylaminopyridine and 1.28 ml methanesulfonyl chloride. The reaction mixture was allowed to warm up to room temperature and stirred at room temperature for two hours. Subsequently the reaction mixture was worked up analogously to Example 3, and the resulting title compound was recrystallized from ethylacetate. There were obtained 4.7 g 3-{4-[4-(2-pyridyl)-piperazin-1-yl]-butylaminocarbonyl)-flavone. yl]-butylaminocarbonyl}-flavone.
