Procedure

A mixture of 2-methylamino-3-nitro-benzoic acid and 10% Pd/C (300 mg) in EtOAc (5 mL) and EtOH (5 mL) was stirred in an atmosphere of hydrogen over night. The mixture was filtered though a pad of Celite and the filter cake was washed with EtOAc. The filtrate was concentrated under reduced pressure to provide 3-amino-2-methylamino-benzoic acid.

Workup

  1. filtrationThe mixture was filtered though a pad of Celite
  2. washthe filter cake was washed with EtOAc
  3. concentrationThe filtrate was concentrated under reduced pressure
