Reaction Steps

To a solution of ethyl (2E,4E)-5-(2,3-dihydro-1,4-benzodioxin-6-yl)penta-2,4-dienoate (5.00 g) in ethanol (100 mL) was added 10% palladium-activated carbon (1.0 g), followed by stirring at room temperature under hydrogen atmosphere (4 atm.) for 5 hours. The catalyst was removed by filtration, and then the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (eluent: hexane/ethyl acetate=85/15) to obtain ethyl 5-(2,3-dihydro-1,4-benzodioxin-6-yl)pentanoate (2.94 g).
