Reaction Steps
16.7 g (0.1 mol) of dichloromaleic anhydride and 19.7 g (0.1 mol) of 2-(4-chlorophenyl)-3-methylbutylamine are stirred in 100 ml glacial acetic acid at 120° C. for 4 hours. The mixture is cooled to 20° C. and 10 ml of water are added. A colorless precipitate separates out, and is filtered off with suction and dried. 21.2 g of dichloromaleic acid N-[2-(4-chlorophenyl)-3-methylbutyl]imide of melting point 91°-92° C. are obtained. A further 10.4 g of imide can also be isolated by stirring the mother liquor with water. The total yield is: 91.3% of theory.
