Versuchsvorschrift

A mixture of 4-acetamido-2-hydroxy-5-nitrobenzoic acid (5 g, 20.8 mmol, 1.00 equiv) and HCl (aq.) (110 mL, 6N) in a 500-mL round-bottom flask was allowed to react, with stifling, for 2 hrs while the temperature was maintained at reflux. The mixture was cooled. The solids were collected by filtration, yielding 3.4 g (82%) of 4-amino-2-hydroxy-5-nitrobenzoic acid as a brown solid.
