Reaction Steps

A mixture of 2-(p-methoxyphenethyl)-3-methyl-4-hydroxybenzofuran (1.3 gm; 4.6 mmoles), potassium carbonate (1.38 gm, 10 mmoles), and allyl bromide (1.2 gm, 10 mmoles) in acetone (50 mL) was refluxed for a period of 5 hours. The solids were filtered off and the filtrate was concentrated in vacuo. The residue was chromatographed on silica gel and eluted with 15% ethylacetate in hexane to yield 0.9 gm of 2-(p-methoxyphenethyl)-3-methyl-4-allyloxybenzofuran, which was used as such for the next step.
