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.
一种制备已知和有价值的2-芳基氨基-2-咪唑啉衍生物的方法,包括将适当取代的苯胺与1-酰基咪唑啉-2-酮缩合,产生一个中间化合物,在水性介质中中和后转化为2-芳基氨基-2-咪唑啉的N-酰基衍生物,然后分解中间化合物或所述的N-酰基衍生物,得到相应的游离芳基氨基-2-咪唑啉衍生物或其盐。
