Procedure
16.7 g (0.1 mol) of dichloromaleic anhydride and 17.0 g (0.1 mol) of 3-(4-chlorophenyl)-propylamine are stirred in 100 ml of glacial acetic acid under reflux for 4 hours. 50 ml of water are added and the mixture is cooled to 20° C. The product is filtered off with suction and dried. 26.1 g (82% of theory) of dichloromaleic acid N-[3-(4-chlorophenyl)-propyl]-imide of melting point 72°-73° C. are obtained.
