Procedure

Ethyl(2E)-3-(2,6-difluoro-4-methoxyphenyl)acrylate (1.1 g, 4.54 mmol) was dissolved in a mixed solvent of tetrahydrofuran (30 mL) and ethanol (30 mL), 10% palladium-carbon (0.30 g) was added and the mixture was stirred under a hydrogen atmosphere at room temperature for 5 hr. The catalyst was filtered off, and the obtained filtrate was concentrated to give the title compound (1.17 g, yield 100%) as a colorless oil.
