Procedure

A solution of 2-nitrobenzene-1,3-diol (5.00 g, 32.2 mmol) in MeOH (100 mL) was stirred under H2 atmosphere (balloon) in the presence of 10% Pd/C (200 mg) for 16 h at room temperature. The reaction mixture was filtered and the filtrate was concentrated to render a residue characterized as 2-aminobenzene-1,3-diol (3.0 g, 95% yield), used as such for the next reaction step.

Workup

  1. filtrationThe reaction mixture was filtered
  2. concentrationthe filtrate was concentrated
