Reaction Steps

A solution of 2-benzyl-3-methyl-5,6-methylenedioxybenzofuran (226 mg, 0.85 mmole) in methylene chloride (10 mL) was cooled at -65° C. and a 1M solution of boron tribromide in methylene chloride (0.85 mL) was added dropwise. The mixture was allowed to warm up to -25° C. and was kept in that range for 1 hour. Methanol (5 mL) was then added and the mixture was evaporated in vacuo. The residue was chromatographed on silica gel and eluted with 25% ethylacetate in hexane to yield 128 mg of 2-benzyl-3-methyl-5,6-dihydroxybenzofuran, mp. 95.5°-98° C.
