反应详情

A mixture of ethyl (2E)-3-(2-fluoro-4-methoxyphenyl)acrylate (7.07 g, 31.5 mmol), tetrahydrofuran (50 mL), ethanol (5 mL) and platinum dioxide (300 mg) was stirred overnight under a hydrogen atmosphere at room temperature. The catalyst was filtered off and the filtrate was concentrated. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=4:1) to give the title compound (5.97 g, yield 84%) as a colorless oil.
