Malononitrile → HCID 178503262, compound

Participants

Reaction Steps

4-[(4-methylsulfanylphenyl)hydrazono]-4H-pyrazole-3,5-diamine was prepared using 108 mg (0.5 mmol) of 2-[(4-methylsulfanylphenyl)hydrazono]malononitrile, which was derived from 4-methylthioaniline (117 mg, 1.0 mmol) and malononitrile (1.5 mmol), and hydrazine hydrate. Precipitate formed in the reaction tube immediately after the addition of hydrazine hydrate. The resulting solid was isolated by filtration, washed with ethanol, and dried to yield 95 mg (77%) of the compound as an orange solid.
