Allyl bromide → HCID 10601391, compound

Participants

Reaction Steps

3-(5-Benzo[b]furanyl)-2'-(β-D-glucopyranosyloxy)-6'-hydroxy-4'-methylpropiophenone (2.50 g) is dissolved in acetone (20 ml), and thereto are added potassium carbonate (2.13 g) and allyl bromide (933 mg), and the mixture is refluxed for 6 hours. After cooling, the reaction mixture is poured into ice-water, and the mixture is extracted with ethyl acetate. The organic layer is washed with water, dried, and concentrated under reduced pressure. The resulting residue is purified by silica gel column chromatography (solvent; chloroform/methanol) to give 3-(5-benzo[b]furanyl)-2'-(β-D-glucopyranosyloxy)-6'-allyloxy-4'-methylpropiophenone (1.63 g).
