摘要:
A method of producing an aromatic amino compound using a primary or secondary amine compound and a halogenated aromatic compound as starting materials, and relying upon the Ullmann reaction, the method being capable of obtaining the highly pure aromatic amino compound in high yields and inexpensively. A primary or secondary amine compound having an aromatic ring group and a halogenated aromatic compound as starting materials, are reacted with the halogenated aromatic compound in the presence of copper catalyst and base to produce the aromatic amino compound having a structure in which an aromatic ring group derived from the halogenated aromatic compound is coupled to the amino group of the amine compound, wherein the amine compound and the halogenated aromatic compound are reacted together such that an aromatic oxycarboxylic acid having a hydroxyl group and a hydroxycarbonyl group bonded to neighboring carbon atoms, is present together with the copper catalyst and the base.
