Procedure

4-(7-Trifluoromethyl-4-quinolinylamino)benzenesulphonyl chloride hydrochloride (3.5 g, 0.008 mol) was added portionwise to a cold (10°), well stirred mixture of 1-(4-fluorobenzoyl)piperazine hydrochloride (2.0 g, 0.008 mol) in chloroform (50 ml) and sodium carbonate (10.0 g) in water (50 ml). The cooling bath was removed and the mixture was allowed to warm to room temperature. After half an hour, the mixture was filtered and the filtrate separated. The chloroform layer was dried (MgSO4). The solvent was removed by evaporation to give a yellow gum. The gum was crystallised from ethanol-water, then purified by column chromatography (basic Al2O3-chloroform) followed by recrystallisation from ethanol, to give the pure title compound (0.9 g), m.p. 172°-174.5° C.
