Procedure

An ethanol (250 ml) solution of 4-ethyl cinnamic acid (34.0 g, 0.191 mol) was hydrogenated at 60 psi over 10% Pd/C (2 g) for 2 hr. The mixture was filtered and concentrated in vacuo to give 3-(4-ethylphenyl)propionic acid as a white solid (34 g, 100%).

Workup

  1. filtrationThe mixture was filtered
  2. concentrationconcentrated in vacuo
