実験手順

This compound was prepared using 94 mg (0.5 mmol) of 2-[(3-fluorophenyl)-hydrazono]malononitrile, which was derived from 3-fluoroaniline (96 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 41 mg (37%) of the title compound as a yellow solid. 1H NMR (ppm, DMSO-d6): 6.2 (br s, 4H), 7.0 (t, 1H), 7.35-7.62 (m, 3H), 10.80 (s, 1H).
