Versuchsvorschrift

5 g (21.8 mmol) of N-carboxymethylene-4-chloro-anthranilic acid are suspended in 50 ml of isopropanol, and 222 mg (2.3 mmol) of sulfuric acid are added. The mixture is heated under reflux for 8.25 hours. It is then cooled to room temperature and the product which has precipitated out is washed with petroleum ether and dried. 4.6 g (16.9 mmol; 78%) of N-carboisopropoxymethylene-4-chloro-anthranilic acid are obtained.
