Procedure

Methyl benzofuran-7-carboxylate (12 g, 68 mmol) was hydrogenated at 60 psi over 10% Pd/C (2 g) in acetic acid (60 ml) for 18 hr. The mixture was filtered, and the filtrate was concentrated in vacuo to give a pale green oil (12 g, 100%),

Workup

  1. filtrationThe mixture was filtered
  2. concentrationthe filtrate was concentrated in vacuo
