Participants

Reaction Steps

To a solution of 4-(3,4-methylenedioxyphenoxy)benzaldehyde (1.7 g, 7.0 mmol) in ethanol (40 mL) was added a solution of semicarbazide hydrochloride (0.82 g, 7.1 mmol) and sodium acetate (0.55 g, 6.7 mmol) in water (10 mL). The mixture was stirred at room temperature for 30 min. The resulting white solid was collected by filtration, washed with water and dried in vacuo to yield the title compound (1.2 g, 4.0 mmol, 57%), mp: 225-226° C. 1H NMR (DMSO-d6): δ 10.17 (s, 1H), 7.80 (s, 1H), 7.70 (d, J=8.7, 2H), 6.93 (d, J=8.3, 1H), 6.92 (d, J=8.7, 2H), 6.77 (d, J=2.4, 1H), 6.53 (dd, J=2.4, 8.3, 1H), 6.44 (s, 2H), 6.06 (s, 2H).
