实验过程

4′,7-Dihydroxyisoflav-3-ene (500 mg, 2.08 mmol) was dissolved in absolute ethanol (10 mL). 4-tert-Butylaniline (311 mg, 2.08 mmol) was added followed by formaldehyde solution (6 mL, 0.04 mol, 37 wt. %). The reaction was stirred at room temperature for 1 day. The white precipitate was collected to afford the title compound (134 mg, 15%).
