Versuchsvorschrift

65 g of 5-chloro-2-nitrobenzonitrile was dissolved in 150 ml of dimethylformamide, and 150 ml of a 50% aqueous solution of dimethylamine was added thereto. After cooling the heat generated, the mixture was stirred at room temperature for 1 hour. The reaction mixture was poured into water, and the precipitate thus formed was collected by filtration, washed with water and then with methanol to obtain 64.5 g of 5-dimethylamino-2-nitrobenzonitrile (melting point: 174°-175° C.).
