Abstract
Process for obtaining new phenothiazine derivatives, characterized in that it starts from the general formula ** in which y represents a hydrogen or halogen atom or an aryl alkyloxy or aryloxy alkyl radical; z a sulfur atom or a so or so radical2; a and b are straight chain or branched divalent aliphatic hydrocarbon radicals containing from 2 to 4 carbon atoms; x represents a halogen atom or an acid residue; r1 r2 r3 r4 represent alkyl radicals with 1 to 4 carbon atoms and can represent * * (see formula) * heterocyclic radicals and the different radicals r can be coupled with the radicals a and b and the nitrogen atoms for the formation of heterocycles.
