Reaction Steps
28 g (0.2 moles) of allylsuccinic acid anhydride, 32.4 g (0.2 moles) of 3,5-dichloroaniline, 0.6 g of triethylamine and 150 ml of xylene are reacted at 125° C., with stirring. The water produced during the reaction is removed azeotropically by way of a water separator. The duration of the reaction is 4 hours. The solvent is subsequently drawn off and the residue is recrystallized from ethyl acetate with the addition of active carbon. The product has a melting point of 121° C. The yield is 89.4% of the theoretical yield.
