Procedure

3-Ethoxy-4-nitrobenzoic acid (0.31 g) was treated with 5% palladium on charcoal under an atmosphere of hydrogen (1 bar) for 3 hours. The reaction mixture was filtered and the filtrate was evaporated to leave the product as a beige solid (0.245 g; MS: ES−(M−H) 180).

Workup

  1. filtrationThe reaction mixture was filtered
  2. customthe filtrate was evaporated
