Abstract: This invention relates to an improved process for making N-(N'-methylenepyrrolidonyl)-2-substituted anilines which are useful intermediates in the synthesis of agricultural herbicides.This process of the invention comprises reacting a 2-substituted aniline with N-chloromethylpyrrolidone at about room temperature in the presence of an acid acceptor. Such room temperature alkylation of the aniline prevents excessive side reactions, particularly with a substituent in the 2-position of the aniline, such as an alkenyl group, which is sensitive to alkylating agents which require excessive heating to effective the condensation reaction.
