Procedure

63.9 g of 5-chloro-2-nitrobenzonitrile was dissolved in 200 ml of dimethylformamide, and 95 ml of piperidine was added to the solution. The mixture was stirred at 50° C. for 30 minutes while externally cooling because of heat generation. The reaction mixture was poured into water, and the precipitate thus formed was collected, washed with water and then with methanol, and dried to obtain 80 g of 2-nitro-5-piperidinobenzonitrile (melting point: 126°-127° C.).
