Versuchsvorschrift
The mixture of 1.4 g of 4-(4-acetamidophenoxy)-3-benzylamino-5-sulfamoylbenzoic acid and 14 ml of 2N aqueous sodium hydroxide is refluxed for 1 hour under nitrogen. After cooling to room temperature it is filtered and the filtrate acidified with glacial acetic acid to pH = 4. The precipitate formed is filtered off and recrystallized from aqueous ethanol, to yield the 4-(4-aminophenoxy)-3-benzylamino-5-sulfamoylbenzoic acid of the formula ##SPC12##
