Procedure

55 g of pentachlorobenzonitrile are introduced into 300 g of ethylenediamine at room temperature in such a way that the temperature does not exceed 30° C. The mixture is then stirred for a further half an hour at room temperature, after which 0.75 l of ice water is slowly added and stirring is continued for 15 minutes. The precipitate is filtered off under suction, washed with water and dried to give 55 g of product which, when recrystallized from toluene with the addition of active carbon, has a melting point of 140°-144° C.
