Procedure

A solution of ethyl 3-benzylamino-4-(4-benzyloxyphenoxy)-5-sulphamyl-benzoate (2 g) in 1N sodium hydroxide (45 ml) was left standing at room temperature for 40 hours. Then the reaction mixture was adjusted to a pH of 2.5 by addition of 4N hydrochloric acid. The precipitated 3-benzylamino-4-(4-benzyloxyphenoxy)-5-sulphamyl-benzoic acid was isolated by filtration and recrystallized from aqueous ethanol. After drying, the compound was obtained with a melting point of 249°-251°C.
