実験手順
A solution of 2-(p-methoxybenzoyl)-3-methyl-4-hydroxy-5-allylbenzofuran (40 mg) in ethanol (50 mL) was hydrogenated in a Parr hydrogenator in the presence of 10% palladium on charcoal at 40 psi. The catalyst was filtered and the filtrate was concentrated to dryness to yield 2-(p-methoxybenzyl)-3-methyl-4-hydroxy-5-propylbenzofuran, identical to the product prepared by the route described in Example 1.
