Abstract
Process for the manufacture of new fentiazine derivatives of the general formula I ** (See formula) ** wherein R means methyl or ethyl and n number 2 or 3, and their salts with pharmacologically harmless acids, characterized in that at high temperature it is reacted A. a fentiazine derivative of the general formula II ** (See formula) ** wherein X is the remainder of a reactable ester, with an imidazolidone derivative of the general formula III ** (See formula) ** where R and n have the same meaning as in formula I, O B. 3-Chloro-Fentiazine with an imidazolidone derivative of the general formula IV ** (See formula) ** in which R and n have the same meaning as in formula I and X the same meaning as in formula II or C. the fentiazine derivative of the general formula V ** (See formula) ** with an imidazolidone derivative of the general formula VI wherein n and R have the same meaning as in general formula I and Hal is a halogen, and the fentiazine derivatives obtained from general formula I are optionally transferred to the salts with pharmacologically harmless acids.
