Isoformononetin → HCID 44227176, compound

Participants

Reaction Steps

A mixture of 7-methoxy-4′-hydroxyisoflavone (1, 0.27 g, 1 mmol), K2CO3 (0.41 g, 3 mmol), epichlorohydrin (0.3 g, 3 mmol) and acetonitrile (30 mL) was refluxed with stirring for 4 hrs (TLC monitoring). The mixture was evaporated in vacuo to give a residue which was treated with H2O (50 mL). The precipitate thus formed was collected, purified by column chromatography (MeOH/CH2Cl2=1:50), and crystallized from EtOH to give the title compound 3 (0.14 g, 43% yield). M.p.: 153-154° C.
