PROCESS FOR PRODUCING ANILINE DERIVATIVE

摘要

A process for producing an aniline derivative represented by general formula (3) by reacting a halogenated aminophenol derivative represented by general formula (1) or a carbonate derivative thereof with an alkylating agent of the formula (R-Y) in the presence of a phase-transfer catalyst in a bilayered system composed of an aqueous solution of an alkali metal hydroxide and an organic solvent, wherein R represents (substituted) C3-C12 cycloalkyl or C3-C6 alkynyl; or a process for producing an aniline derivative represented by general formula (3) by reacting an aminophenol derivative represented by general formula (1) with an alkylating agent in the presence of an alkali metal carbonate in an organic solvent. The process enables an intermediate for producing an oxazolidinedione derivative useful as the active ingredient of a herbicide to be efficiently produced without the necessity for protecting the amino group.
