실험 절차
4′,7-Dihydroxyisoflav-3-ene (501 mg, 2.09 mmol) was dissolved in ethanol (15 ml). Aniline (0.25 ml, 2.74 mmol) was added followed by formaldehyde solution (2 ml, 0.03 mol, 37% wt.). The reaction was stirred at room temperature for 3 days. The white precipitate was collected to afford the title compound (53 mg, 7%).
