In 20 ml of ethanol were dispersed 1.59 g of 2-hydrazino-5-nitropyridine and 1.13 g of benzaldehyde. The dispersion was refluxed at 100° C. for 16.5 hours. The reaction solution was allowed to cool at room temperature. The resulting precipitate was collected by suction filtration, washed with ethanol and air dried, obtaining 1.55 g (yield 62%) of orange yellow fine acicular crystals.
