Reaction Steps
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 oxide (300 mg) was stirred overnight at room temperature under a hydrogen atmosphere. The catalyst was filtered off, and the filtrate was concentrated. The residue was purified by silica gel column chromatography (20% ethyl acetate/hexane) to give the title compound (5.97 g, yield 84%) as a colorless oil. 1H NMR (CDCl3) δ: 1.23 (3H, t, J=7.2 Hz), 2.58 (2H, t, J=7.6 Hz), 2.90 (2H, t, J=7.6 Hz), 3.77 (3H, s), 4.12 (2H, q, J=7.2 Hz), 6.57-6.63 (2H, m), 7.07-7.13 (1H, m).
