Malononitrile → HCID 178438978, compound

Participants

Reaction Steps

4-[(2-isopropylphenyl)hydrazono]-4H-pyrazole-3,5-diamine was prepared using 106 mg (0.5 mmol) of 2-[(2-isopropylphenyl)hydrazono]malononitrile, which was derived from 2-isopropylaniline (142 μL, 1.0 mmol) and malononitrile (1.5 mmol), and hydrazine hydrate. Precipitate formed in the reaction tube approximately 5 minutes after the addition of hydrazine hydrate. The resulting solid was isolated by filtration, washed with ethanol, and dried to yield 90 mg (73%) of the compound as a greenish yellow solid.
