摘要

Procedure for the obtaining of ammonium salts of substitute 1,1-dioxides of 3,4 dihydro-2H-1,2-benzotizazine. A compound (I) or a salt of the same with a lower dialcyl-di- (hydroxy-lower rent) - or tri- (hydroxy-lower rent) -amine or a salt of it is reactioned. Compound is obtained (II) where ph is a rest 1,2-phenylene in case of replaced, r is a heteroalquil rest that can be replaced; r is hydrogen or a hydrocarbon remain of aliphatic character that can be replaced; am 022 is the ammonium cation derived from a lower dialcylene, -; di- (hydroxy) -lower or tri- (hidroxy-lower rent) -amine, am-h pharmaceutically used.
