Versuchsvorschrift

3.5 g of 3-hydroxy-5-phenyl-isoxazole were dissolved in 100 ml of dimethylformamide. The solution was reacted with 3 g of finely powdered potassium carbonate and the reaction mixture was heated for 15 minutes at 100° C. in a nitrogen atmosphere. Then 5.8 g of 3-[N-(2-(3,4-dimethoxyphenyl)-ethyl)-N-methylamino]-propyl chloride were added batchwise. The reaction mixture was stirred for 4 hours at 100° C., after which the salts that formed were filtered off, the filtrate was concentrated to dryness, and the residue dissolved in methyl-tert-butyl ether. The solution was then washed with aqueous sodium carbonate solution, dried with magnesium sulfate, and concentrated to dryness. The remaining crude oily title compound that was left as a residue was purified by flash chromatography using ethyl acetate as the eluent. 4.75 g of the title compound were obtained.
