Reaktionsschritte

4-(7-Chloro-4-quinolinylamino)benzenesulphonyl chloride hydrochloride (5.4 g, 0.014 mol) was added portionwise to a well-stirred two phase mixture of chloroform/water (140 ml/140 ml) containing sodium carbonate (14.8 g) and 2-aminomethyl-1-propylpyrrolidine (2.0 g, 0.014 mol) at about 10° C. The mixture was allowed to warm to room temperature, then stirred for 11/2 hours. The chloroform layer was separated, dried (MgSO4) and evaporated under reduced pressure to give a gum. The gum was crystallised from ethanol/water to give a pale yellow solid (1.8 g). A further recrystallisation from ethanol gave the title compound (0.5 g), melting point 192.5°-194° C.
