Process for the manufacture of 2-arylamino-2-imidazoline derivatives and their salts |
摘要 |
A process for the preparation of the known and valuable 2-aryl-amino-2-imidazoline derivatives which comprises condensing an appropriately substituted aniline with a 1-acyl-imidazolidin-2-one to produce an intermediate compound which on neutralisation in an aqueous medium is converted into a N-acyl derivative of the 2-aryl-amino-2-imidazoline, and splitting the intermediate compound or the said N-acyl derivative to give the corresponding free arylamino-2-imidazoline derivative or a salt thereof.
