Zusammenfassung:Novel Arylaminoimidazoline derivatives of the formulas in which R1 and R2 are halogen or an alkyl group with 1 to 4 C atoms, R3 is hydrogen or an alkyl radical with 1 - 4 C atoms and n and m each represent an integer from 1 to 3, the sum of n + m being an integer from 2 to 5 inclusive, and their salts, are prepared by reacting aniline derivatives of the formula with 1-acylimidazolidine-2-one of the formula in the presence of phosphorus oxychloride. This novel compounds have a pronounced analgesic action. O.Z.647/A
