Abstract

Process for the manufacture of new phenothiazine compounds, characterized in that it comprises reacting a compound of the general formula ** (See formula) ** with a compound of the general formula ** (See formula) ** or reacting 2-trifluoromethyl-phenothiazine, in the presence of an acid-binding agent, with a reactive ester of a compound of the general formula ** (See formula) ** or treating 2-trifluoromethyl-phenothiazine with phosgene, reacting the 2-trifluoromethyl-10-cyclocarbonyl-phenothiazine formed with a compound of the general formula ** (See formula) ** and the decarboxylation by heating the product obtained, or reacting a reactive ester of a compound of the general formula ** (See formula) ** with an amine of the general formula ** (See formula) ** in which formulas n represents 1 or 2, one of the symbols n1 and n2 represents 0 while the other symbol represents 0 or 1, one of the symbols X and Y represents halogen, while the other represents the group -OMe, in which Me represents an alkali metal, A and B represent lower straight or branched chain lower alkylene, and R1 and R2 represent lower alkyl or, taken together with nitrogen, a 5- or 6-membered heterocyclic containing 1 or 2 nitrogen atoms, or a 5- or 6-membered heterocyclic ring, substituted by lower alkyl and containing 1 or 2 nitrogen atoms, in which case one of the alkyl radicals represented by the symbols R1 and R2 can be introduced later into the molecule by reaction of the secondary amine with a low molecular weight alkylating agent, and, if desired, transforming into a salt the product obtained.
