A process for preparing p.chlorophenoxyacetyl-piperonylpiperazine ("Fipexide"), consisting of reacting, p.chlorophenoxyacetyl chloride directly with piperonylpiperazine in the presence of an inert reaction solvent, in particular chloroform, but in the absence of substances acting as acid acceptors. The p.chlorophenoxyacetyl chloride can be formed directly in situ, from p.chlorophenoxyacetic acid and thionyl chloride. |
