Abstract
The invention comprises N4-dialkylsulphamoyl-sulphanilamides of the formula <FORM:0792561/IV (b)/1> in which R and R1 are alkyl radicals, R2 is hydrogen or an alkyl radical and R3 is hydrogen or an alkyl, amidino or heterocyclic radical and the preparation of these compounds by heating a sulphanilamide of the formula <FORM:0792561/IV (b)/2> with a sulphamoyl halide of the formula <FORM:0792561/IV (b)/3> e.g. with a dialkylsulphamoyl chloride, preferably at a temperature of 80 DEG C. to 150 DEG C. in the presence of an acid acceptor such as pyridine. Examples describe the preparation of the N4-dimethylsulphamoyl-, N4-diethylsulphamoyl- and N4-dipropylsulphamoyl derivatives of sulphanilamide and N4-dimethylsulphamoyl-N1-butylsulphanilamide; N4-dimethylsulphamoyl-N1 : N1-dimethylsulphanilamide; N4-dimethylsulphamoyl - N1 - guanylsulphanilamide; N4 - dimethylsulphamoyl - N1 - (2 - pyrimidyl) - sulphanilamide and N4 - dimethylsulphamoyl-N1-(2-thiazolyl)-sulphanilamide. Starting materials. Dimethylsulphamoyl chloride is made by the reaction of dimethylamine with sulphuryl chloride.
