Versuchsvorschrift

4-(7-Chloro-4-quinolinylamino)benzenesulphonyl chloride hydrochloride (7.8 g, 0.02 mol) was added portion-wise with stirring to a cold mixture of 1-(4-fluorobenzoyl) piperazine hydrochloride (4.9 g, 0.02 mol) in chloroform (250 ml) and sodium carbonate (24.4 g) in water (250 ml). The cooling bath was removed and the mixture was allowed to warm to room temperature. After 1 hour the chloroform layer was separated and dried (MgSO4). The solvent was removed by evaporation to give a brown gum. Crystallisation from ethanol gave the pure title compound (0.53 g), m.p. 235°-237° C.
