Abstract
Herbicidal N-(haloacetyl)-N-(N'-methylenepyrrolidonyl)-2-alkoxyanilines are provided in this invention having the formula: ##STR1## where R is alkyl of 1-6 carbon atoms, R' is hydrogen or lower alkyl of 1-3 carbon atoms, and X is halogen. Another feature of the invention is the provision of N-(N'-methylenepyrrolidone)-2-alkoxyaniline or intermediates useful in making such herbicides. These intermediates are prepared by reaction of a 2-alkoxyaniline with an N-methylolpyrrolidone or an N-halomethylenepyrrolidone. The herbicide product than is obtained by acylation of the intermediate with a haloacetyl halide. The compounds of the present invention show good herbicidal activity against grassy weeds.
