Procedure
Lead tetraacetate (200 mg) was added to a solution of 6-hydroxy-3-(3,4,5-trimethoxyphenyl)-5-propyl-2,3-dihydrobenzofuran (100 mg) in dry methanol (10 ml), and the mixture was stirred at room temperature for 1 hour. The solution was evaporated to a residue, which was put on a flash column of silica gel and eluted with hexane-ethyl acetate (4:1, v/v). The title compound was isolated as a mixture of epimers.
