3,4-Dichloroaniline → HCID 178509185, compound

Participants

Reaction Steps

This compound was prepared using 120 mg (0.5 mmol) of 2-[(3,4-dichlorophenyl)-hydrazono]malononitrile, which was derived from 3,4-dichloroaniline (162 mg, 1.0 mmol) and malononitrile (1.5 mmol) as described in Example 8, and hydrazine hydrate. Precipitate formed in the reaction tube immediately after the addition of hydrazine hydrate. The resulting solid was isolated by filtration, precipitated from an ethyl acetate solution by the addition of hexanes, and dried to yield 53 mg (39%) of the title compound as a yellow solid. 1H NMR (ppm, DMSO-d6): 6.30 (br, s, 4H), 7.55-7.79 (m, 2H), 7.95 (s, 1H), 10.80 (s, 1H).
