Abstract
Provided is a method of producing an aromatic amide derivative represented by Formula (I), which method includes a process a containing reacting an aniline derivative represented by Formula (II) with a carboxylic acid derivative represented by Formula (III) in the presence of a base to obtain an imide compound represented by Formula (IV) and a process b containing hydrolyzing the imide compound represented by Formula (IV) to obtain the aromatic amide derivative represented by Formula (I): wherein R1 represents a C1-C4 haloalkyl group, etc.; each of R2 and R3 independently represents a hydrogen atom, a halogen atom, etc.; R4 represents a hydrogen atom, a C1-C4 alkyl group, etc.; each of X1 and X2 independently represents a halogen atom, a C1-C4 haloalkyl group, etc.; and Q represents a C1-C4 alkyl group, a phenyl group, a pyridyl group, etc.
