Reaction Steps

5% palladium-carbon (0.1 g) was added to a solution of ethyl 5-(5-acetoxy-2,3-dihydro-6,7-dimethoxy-2,4-dimethylbenzofuran-2-yl)pentadienoate (1.3 g) in ethanol (30 ml), and the mixture was stirred under an atmosphere of hydrogen at 50° C. for 5 hours. The reaction mixture was filtered, and the filtrate was concentrated under reduced pressure. The residue was purified by column chromatography on silica gel (hexane:ethyl acetate 7:3) to obtain the title compound (1.1 g, 86%) as an oil.
