Reaction Steps

To a mixture of m-anisaldehyde (544 mg, 4.0 mmol) and malononitrile (264 mg, 4.0 mmol) in ethanol (10 mL) was added piperidine (0.4 mL) and 2,3-diaminophenol (496 mg, 4.0 mmol). The mixture was stirred at room temperature under argon for 2 h, then it was diluted with water (20 mL). The precipitate was filtered to yield 1.08 g (88%) of the title compound as a brown solid. 1H NMR (CD3OD): 8.02 (s, 1H), 7.05 (t, J=7.8 Hz, 1H), 6.58–6.66 (m, 3H), 6.30 (d, J=7.8 Hz, 1H), 6.08 (d, J=7.8 Hz, 1H), 4.41 (s, 1H), 3.60 (s, 3H).
