Sulfonamide-substituted chromans, processes for their preparation, their use as a medicament or diagnostic, and medicament comprising them

Compounds I ##STR1## with R equal to hydrogen or (C.sub.1 -C.sub.4)-alkyl,

N-substituted 5-nitroanthranilic acids, a process for their preparation,

A description is given of a process for the preparation of a compound of the formula I ##STR1## in which R.sup.1, R.sup.2 and R.sup.3 (identical or different) represent H, alkyl having 1-2 carbon atoms and F, Cl, Br or I;

N-substituted aminoalkanoic acids, a process for their preparation,

A description is given of the use of amino-substituted benzoic acid derivatives of the formula I ##STR1## in which R.sup.1 and R.sup.2 denote hydrogen, (cyclo)alkyl, unsubstituted or substituted phenyl or naphthyl, or R.sup.1 and R.sup.2 together denote a chain --(CH.sub.2).sub.m -- with m=3 to 6, or together denote a chain --(CH.dbd.CH).sub.n -- with n equal to 2 or 3; R.sup.3 denotes hydrogen, halogen or alkyl; R.sup.4 denotes hydrogen or NO.sub.2 ; R.sup.5 denotes hydrogen or a radical which can be eliminated under physiological conditions; for the preparation of a remedy for diarrhea.
