Abstract

PURPOSE: To prepare the titled compound useful as a herbicide, economically, in high yield, in an industrial scale, by reacting an alkali metal salt of an oxime with an alkyl halide or a dialkyl sulfate in the presence of a tertiary amine or a quaternary salt.
CONSTITUTION: An alkali metal salt of an oxime of formula I (R1 and R2 are lower alkyl; X is lower alkylene; n is 0 , 1 or 2) is made to react with an alkyl halide of formula R3Y (R3 is lower alkyl; Y is halogen) or a dialkyl sulfate of formula II in the presence of a tertiary amine or a quaternary salt at room temperature or with heating, under agitation. After reaction, concentrated hydrochloric acid is added to the reaction mixture and stirred for 1 to several hours at pH 1, and the reaction mixture is separated into organic phase and an aqueous phase. The organic phass is extracted with an alkali to separate into an alkali-soluble part and an alkali- insoluble part. The titled compound of formula III can be obtained by acidifying the soluble part, or treating the by-product of formula IV existing in the insoluble part with an acid.
