Reaktionsschritte

120 mg (0.31 mmol) of ethyl 2,4-dichloro-5-(2-chloro-4,6-difluorophenylamino)benzoate were suspended in 6 ml of an ethanol/2 N sodium hydroxide solution mixture (1:1) and heated at 90° C. for 3 hours. After cooling to room temperature, the pH was adjusted to 2 with 2 N sulfuric acid, and the precipitate was filtered off with suction. 98 mg (88%) of the product were obtained.
