A process for the manufacture of sulfamoyl anthranilic acids of the general formula I ##STR1## in which Ph is phenyl substituted with 1 or 2 halogen atoms, alkyl groups or etherified hydroxy groups, and R is aralkyl, heteroaralkyl or cycloalkyl-alkyl, unsaturated in the aliphatic moiety, including oxygen or sulfur and/or substituted with halogen, alkyl or alkoxy in the aromatic moiety, by reacting carboxylic acids with at least one mol-equivalent of an amine (R--NH.sub.2) at a temperature above 120.degree. C.
