Procedure

A solution of 2-(p-methoxybenzoyl)-3-methyl-6-benzyloxy-7-propylbenzofuran (1.04 gm, 2.5 mmoles) in ethanol (100 mL) was hydrogenated in a Parr hydrogenator in the presence of 10% palladium on charcoal for a period of 24 hours. The catalyst was filtered off and the filtrate was concentrated in vacuo. The residue was purified by chromatography on silica gel and eluted with 25% ethylacetate in hexane to yield 110 mg of 2-(p-methoxybenzyl)-3-methyl-6-hydroxy-7-propylbenzofuran.
