Malononitrile → HCID 178509188, compound

Participants

Reaction Steps

This compound was prepared using 103 mg (0.5 mmol) of 2-[(3,4-difluorophenyl)-hydrazono]malononitrile, which was derived from 3,4-difluoroaniline (99 μL, 1.0 mmol) and malononitrile (1.5 mmol) as described in Example 8, and hydrazine hydrate. Precipitate formed in the reaction tube approximately 5 min after the addition of hydrazine hydrate. The resulting solid was isolated by filtration, washed with ethanol, and dried to yield 45 mg (38%) of the title compound as a yellow solid. 1H NMR (ppm, DMSO-d6): 6.18 (br s, 4H), 7.28-7.55 (m, 2H), 7.70-7.82 (m, 1H), 10.80 (br s, 1H).
