    Abstract: 5-Sulfamoyl-orthanilic acids (I; R = cl, Br, methyl, phenoxy, phenylthio radical; Ar = furyl, thienyl radical; Z = H, metallic ion, ammounium ion, alkyline metallic ion; X = halogen; ph = substituted aromatic radical; Hal = halogen, Zl = H, metal, ammounium, ter-ammonium), having diuretic activity, were prepd. by reacting compd.(IV) with benzene sulfonic acid (V). The compd. (IV) was obtained from the reaction of compd. (II) and phenyl benzene sulfonate(III).
