Abstract

La présente invention a pour objet un procédé de préparation d'amines aromatiques substituées, consistant à effectuer l'amination directe à l'aide de N-chloro-amines dans un système de type Redox. Elle est caractérisée en ce qu'un composé aromatique disubstitué en 1,4 comprenant un groupe éther et un groupe acylamino est amené à réagir avec une N-chloro-amine dans un milieu réactionnel acide dû à un acide fort. Elle se rapporte aux composés ainsi obtenus.The present invention relates to a process for the preparation of substituted aromatic amines, consisting in carrying out the direct amination using N-chloro-amines in a Redox type system. It is characterized in that a 1,4-disubstituted aromatic compound comprising an ether group and an acylamino group is reacted with an N-chloro-amine in an acidic reaction medium due to a strong acid. It relates to the compounds thus obtained.
