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) ora carbonate derivative thereof with an alkylating agent of the formula (R-Y) in thepresence of a phase-transfer catalyst in a bilayered system composed of an aqueoussolution 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 anilinederivative represented by general formula (3) by reacting an aminophenol derivativerepresented by general formula (1) with an alkylating agent in the presence of an alkalimetal 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.
