Reaction Steps

To a solution of tert-butyl 3-(4-cyano-3-methoxyphenyl)acrylate obtained in step 1 (3.5 g) in ethyl acetate (150 mL) was added palladium on carbon (500 mg) and the mixture was put under a pressure of 4 kg of hydrogen for 12 h at RT. The catalyst was removed by filtration and the solvents were removed under vacuum to afford the title compound as white solid (3.5 g, 97%). 1H-NMR (CDCl3, 400 MHz) δ 7.41-7.43 (1H, s), 6.80-6.83 (2H, m), 3.88 (3H, s), 2.89-2.93 (2H, t), 2.51-2.55 (2H, t), 1.34 (9H, s). LC/MS: 279.1 (M+H)+. HPLC (Method C) Rt 2.40 min (Purity: 99.7%).
