Versuchsvorschrift

A mixture of 3-n-butylamino-4-phenoxy-5-sulphamyl-benzoic acid (3 g) and methanol (60 ml) was saturated with gaseous hydrogen chloride. The reaction mixture was allowed to warm during the saturation. After cooling and standing for 5 hours, the reaction mixture was evaporated in vacuo, and the residue was recrystallized from methanol (12 ml), whereby the methyl-3-n-butylamino-4-phenoxy-5-sulphamyl-benzoate was obtained with a melting point of 148° C.
