Method for producing aromatic diamine derivative

摘要

The invention provides a method for efficiently producing an aromatic diamine derivative represented by formula (3) at high yield, the method including reacting an aromatic amide represented by formula (1) with an aromatic halide represented by formula (2): (wherein each of Ar, Ar¹ and Ar² represents a substituted or unsubstituted aryl group or heteroaryl group; Ar³ represents a substituted or unsubstituted arylene group or heteroarylene group; and X represents a halogen atom).
