AROMATIC AMINO COMPOUND MANUFACTURING METHOD

Title:

AROMATIC AMINO COMPOUND MANUFACTURING METHOD

Document Type and Number:

WIPO Patent Application WO/2010/090094

Kind Code:

A1

Abstract:

Provided is a method for manufacturing an aromatic amino compound by means of the Ullmann reaction using a primary or secondary amine compound and a halogenated aromatic compound as the starting materials with which a high-purity aromatic amino compound can be obtained inexpensively with high yield. In a method in which a primary or secondary amine compound having an aromatic cyclic group and a halogenated aromatic compound are used as the starting materials, and said amine compound and said halogenated aromatic compound are reacted in the presence of a copper catalyst and a base to manufacture an aromatic amino compound having a structure in which an aromatic cyclic group derived from said halogenated aromatic compound is coupled to an amino group of said amine compound, an aromatic oxycarboxylic acid wherein a hydroxy group and a hydroxycarbonyl group are coupled to mutually adjoining carbon atoms is used to cause the aforementioned amine compound and the halogenated aromatic compound to react under conditions wherein the aforementioned copper catalyst and the base are both present.
