실험 절차
A mixture of 3-amino-4-phenoxy-5-sulphamyl-benzamide (1 g) and 1N sodium hydroxide (20 ml) was refluxed for 1 hour. After cooling, the 3-amino-4-phenoxy-5-sulphamyl-benzoic acid was precipitated from the reaction mixture by addition of 4N hydrochloric acid until pH 2.5. After several recrystallizations from aqueous ethanol and drying, the compound was obtained with a melting point of 252°-253°C.
