実験手順

To a solution of ethyl 3-(5-(benzyloxy)-2-methylphenyl)acrylate (1.00 g) in methanol (50 mL) was added 10% palladium-activated carbon (150 mg), and the mixture was stirred for 15 hr under a hydrogen atmosphere. The reaction mixture was filtered, and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (500 mg) as a yellow oil.
