Versuchsvorschrift

A mixture of 7 g of methyl 3-(8-trifluoromethyl-4-quinolylamino)-2-thiophene-carboxylate, 6.17 g of 4-(3-trifluoromethylphenyl)-1-piperazine-ethanol and 50 ml of anhydrous toluene was refluxed for an hour while passing condensed toluene through a column filled with siliporite and the mixture was cooled to 60° C. 150 mg of sodium hydride were added and the mixture was refluxed with stirring for 10 hours. The toluene was distilled and the residue was extracted with ether, washed with water and dried. The product was crystallized from methylene chloride to obtain 10.9 g of 2-[4-(3-trifluoromethylphenyl)-1-piperazinyl]-ethyl 3-(8-trifluoromethyl-4-quinolylamino)-2-thiophene-carboxylate.
