Abstract

Pharmaceutical intermediate, N-phenyl-piperazines of formula (I) (R = H, halogen, tri:fluoro-methyl-, low carbon-alkyl- or alkoxy-gp.; n = 1 or 2), are prepd. via cyclo-condensation of aniline -hydrochloride (II) and di:ethanolamine (III). The reaction proceeds in the presence of di:phosphorus -pentoxide condensing agent and of a phlegmatising agent.
