  • Publication number: 20180362447
    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.

  • Patent number: 9353046
    Abstract: Provided is a method for producing an aromatic amide derivative represented by Formula (4), the method including a process in which an aromatic amide derivative represented by Formula (1) and a haloalkyl compound represented by Formula (3) are reacted with each other in the presence of a base and a metal or metal salt. In the formulae, each of X and Y represents a hydrogen atom, a halogen atom, or the like. A represents a hydrogen atom, an alkyl group, a group represented by Formula (2), or the like. Each of G1 and G2 represents an oxygen atom or the like. Q1 represents a phenyl group or the like. R1 represents a hydrogen atom, an alkyl group, or the like. Z1 represents a haloalkyl group or the like. Xa represents an iodine atom or the like. m represents a number of from 1 to 4, n1 represents a number from 1 to 5, and n2 represents a number of from 1 to 4.
