Versuchsvorschrift
To a solution of ethyl 4-benzyloxy-2-ethylbenzoate (0.633 g) in ethanol (6.2 mL) was added 10% palladium-carbon (0.227 g), and the mixture was stirred at room temperature for 1.2 hrs under an atmosphere of hydrogen. The catalyst was removed by filtration, and the filtrate was concentrated in vacuo. The residue was purified by silica gel column chromatography (eluent: ethyl acetate/n-hexane=1/8) to afford the title compound (0.224 g).
