Versuchsvorschrift
To palladium on activated charcoal (10 wt %, 2.5 g) was added a solution of (E)-3-(3,5-difluorophenyl)acrylic acid (25 g) in a mixture of ethyl acetate (100 mL) and ethyl alcohol (400 mL). The mixture was put on hydrogenator on 50 psi for 6 h. The catalyst was filtered and the solvent was removed to give 25.0 g the title compound (99% yield): 1H NMR (CDCl3, 500 MHz) δ 2.67 (2H, t, J=10 Hz), 2.93 (2H, t, J=10 Hz), 6.65 (1H, m), 6.72 (2H, m).
