Reaction Steps

To a mixture of 3-dimethylaminophenol (489 mg, 3.56 mmol), piperonal (535 mg, 3.56 mmol), and malononitrile (233 mg, 3.53 mmol) in ethanol (20 ml) was added piperidine (0.70 ml, 7.1 mmol). The mixture was stirred at room temperature for 2 h and the resulting solid was collected by filtration, washed with methanol and dried in vacuo to yield the title compound as a yellow solid (940 mg, 2.80 mmol, 79%). 1H NMR (DMSO-d6): 6.83-6.77 (m, 4H), 6.66-6.64 (m, 2H), 6.47-6.44 (m, 1H), 6.21 (s, 1H), 5.96 (s, 1H), 5.95 (s, 1H), 4.53 (s, 1H), 2.85 (s, 6H).
