Procedure

A solution of 4,5-dimethyl-1H-indole-2,3-dione (9.8 g, 0.056 mmol) and sodium hydroxide (8.1 g, 0.2 mol) in water (80 ml) was heated to 85° C., and then 10% aqueous hydrogen peroxide (43 ml) was slowly added. The obtained solution was stirred at 85° C. for 2 hours and then cooled to room temperature and filtered. Sulfuric acid was used for acidification of the filtrate to obtain 6-amino-2,3-dimethylbenzoic acid as crystals.
