Abstract
Phenthiazine derivatives of the formula <FORM:0632277/IV (b)/1> where n is a small integer greater than 1, R1 and R2 are H or alkyl groups, D is the residue of a heterocyclic nucleus in which there may be a second hetero atom, and wherein either of the benzene rings may contain alkyl or alkoxy groups, are prepared by reacting the phenthiazine with the compound <FORM:0632277/IV (b)/2> where X is halogen, in the presence of an acid acceptor such as sodamide and, if desired, an organic diluent such as xylene. In examples: (1) b -piperidino-ethyl-N-phenthiazine is prepared from phenthiazine and 1-chloro-2-piperidino-ethane, and (2) b -morpholino-ethyl-N-phenthiazine from phenthiazine and 1-chloro-2-morpholino-ethane.
