Abstract

1382752 2 - Arylamino - 2 - imidazolines STAR AB OY 11 May 1973 [19 May 1972] 22687/73 Heading C2C 2-Arylamino-2-imidazolines of the general formula wherein each of R 1 , R 2 , R 3 and R 4 is a hydrogen or chlorine atom or a methyl group, at least two of them being hydrogen atoms, and acid addition salts thereof are prepared by reacting an aniline of the general formula with an equivalent amount of 2-imidazolidinone in the presence of an excess of phosphorus oxychloride in an anhydrous inert aromatic hydrocarbon at its reflux temperature for 10-20 hours, followed optionally by salification of the product.
