Reaction Steps

Ethyl 4',5,7-trihydroxy-2-isoflavonecarboxylate (100 mg) was added to 10 ml of isopropanol saturated with HCl gas, and the mixture was heated at 70° C. with stirring for five hours. The solvent was distilled off under reduced pressure, the residue was purified by silica gel column chromatography (eluent: chloroform), and the solid thus obtained was recrystallized from a chloroform/methanol mixed solvent, giving 60 mg of isopropyl 4',5,7-trihydroxy-2-isoflavonecarboxylate.
