  Process for the preparation of a new benzenesulfonamide derivative. Subject of the present patent forms an ancestor for the preparation of a new Benzolsulif onamidderivates, which there - is characterized by ,,

  that one compound of the formula
EMI0001.0013
    where R is an acyl group and X is a residue which is split off during the reaction, such as.

   B. an acylsulfanilic acid halide, to a compound of the formula
EMI0001.0021
    in which Y represents a radical which splits off during the reaction, allows it to act and treats the compound obtained with hydrolyzing agents.

   The 2- (p-aminobenzenesulfonamlo) - thio, diazole - (1,3,4) thus obtained. shows the F.218-219. It is soluble in alkalis as well as acids and gives the diazo reaction.



  The new compound is intended to be used therapeutically. The condensation can occur in the presence or absence of. indifferent solvents or im. Presence of water. As a solvent let see z. B.

    Use ether, diogan, petroleum ether, benzene, toluene, xylene, chlorobenzene, nitrobenzene, tetraahlorethane. It is also possible to work in the presence of condensation agents or catalysts.

   The implementation can, for example, with alkaline .reagie- rende agents., Such as alkalis, and alkaline earths, organic bases, z. B. tertiary bases such as pyridine, and @dergleiehen.



  For the hydrolysis, alkaline or acidic agents, for example alkali or alkaline earth metal hydroxides, such as sodium or calcium hydroxide or acids, e.g.

   B. hydrochloric acid in the presence of water or organic solvents such as alcohol can be used.



  The 2 -, (p, -aminobenzolsul @ fon- ami @ do) -thadiazole = (1,3,4) can be used as such or in the form of its salts, e.g. B., of Na trium, calcium or hydrochloric acid, isolate.

           Example: 10 parts of 2-aminothiodiazal (1,3,4) who added to 25 parts of pyridine and gradually admixed with 23.5 parts of p - acetylaminobenzene sulfochloride with stirring.

         It is then heated to 95 for half an hour. The condensation product is obtained in solid form by pouring the resulting solution into ice water.

       It is sucked off and @durah boiling is saponified in dilute sodium hydroxide solution. The 2i- (p-aminobenzalsulfonamide @ a) -thio, diiazole- (1,3,4) precipitated with acetic acid ha: t after recrystallization from aqueous alcohol, F.218 to 219.
