Procedure
10.6 g of N-carboxymethylene-6-fluoro-anthranilic acid having a purity of 73% (corresponding to 39.6 mmol) are suspended in 25 ml of ethanol, 0.98 g (9.6 mmol) of concentrated sulfuric acid are added and the reaction mixture is heated under reflux for 6 hours. It is cooled to room temperature and the product which has precipitated out is filtered off with suction, washed with ethanol and dried.
