Reaction Steps

To a solution of 4-acetyloxy-6-(6-(benzyloxy)benzofuran-2-yl)-3,5-dimethyl-2H-pyran-2-one (500 mg) in EtOH (50 ml) and 1,4-dioxane (50 ml) there was added 10% Pd/C (100 mg), and the mixture was vigorously stirred at room temperature for 3 hours under a hydrogen gas atmosphere. The reaction solution was celite filtered, and then the filtrate was concentrated under reduced pressure and the residue was purified by silica gel column chromatography (n-hexane/AcOEt=1/1) to obtain 4-acetyloxy-3,5-dimethyl-6-(6-hydroxybenzofuran-2-yl)-2H-pyran-2-one.
