Participants

Reaction Steps

4-[(3-Nitrophenyl)hydrazono]-4H-pyrazole-3,5-diamine was prepared using 2-[(3-nitrophenyl)hydrazono]malononitrile (0.107 g, 0.5 mmol) which was derived from 3-nitroaniline (0.133 g, 1.0 mmol) and malononitrile (1.5 mmol) in a manner similar to that described in Example 2, and hydrazine hydrate. The resulting solid (0.088 g) was isolated by filtration, a portion (0.060 g) of which was purified by flash chromatography to yield 0.024 g (28%) of the title compound as an orange solid; MS (m/z, ES+): 248.0 (M+1, 100%).
