Procedure

99 g of malononitrile were dissolved in 150 ml of DMF and cooled to 0° C. While cooling, 306 g of triethylamine and 159 g of chloroacetyl chloride were simultaneously added dropwise to this. The reaction mixture was stirred at 10° C. for 10 minutes and subsequently added to a mixture of 1.5 kg of ice and 158 g of isopropylamine. The mixture was stirred at room temperature for 8 hours. The volatiles were then removed by distillation under atmospheric pressure at 100° C., and the distillation residue was cooled to 5° C. The precipitate was filtered off with suction, washed and dried. 105.6 g (43% of theory) of the compound of the formula ##STR24## of melting point 285° to 290° C. were obtained. The IR, NMR, UV and mass spectra and the elemental analysis are consistent with the structural formula.
