실험 절차
The mixture of 1.5 g of 4-(3-acetamidophenoxy)-3-n-butylamino-5-sulfamoylbenzoic acid and 15 ml of 2 N aqueous sodium hydroxide is refluxed for 5 hours under nitrogen. After cooling it is filtered, the filtrate acidified with glacial acetic acid and hydrochloric acid to a pH of 2 - 3, the precipitate collected and recrystallized from ethanol, to yield the 4-(3-aminophenoxy)-3-n-butylamino-5-sulfamoylbenzoic acid of the formula ##SPC16##
