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.
This invention relates to novel N-(N'-methylenepyrrolidonyl)-2-substituted anilines which are useful intermediates in the synthesis of herbicides. The intermediate compounds of the invention have the formula: ##STR1## Where R is alkyl, C.sub.1 -C.sub.6, alkenyl, C.sub.3 -C.sub.5, alkyleneoxyalkyl, --(CH.sub.2).sub.n OR", where n=1-3, and R" is alkyl, C.sub.1 -C.sub.3, and cycloalkyl, ##STR2## where n'=0-3, R' is hydrogen or alkyl, C.sub.1 -C.sub.3, and, Y is oxygen or sulfur.
This invention relates to aryl carbonyl derivatives which are activators of glucokinase which may be useful for the management, treatment, control, or adjunct treatment of diseases, where increasing glucokinase activity is beneficial.
The invention provides novel GlyT2 inhibiting compounds useful in modulating, treating, or preventing: anxiolytic disorders; a condition requiring treatment of injured mammalian nerve tissue; a condition amenable to treatment through administration of a neurotrophic factor; a neurological disorder; or obesity; an obesity-related disorder.
