PURPOSE: To obtain the titled compound useful as an agricultural and horticultural germicide and insecticide in high yield, by hydrolyzing a reaction product of an alkoxyiminoacetic ester with an aromatic amine under neutral or alkaline conditions.
CONSTITUTION: An alkoxyiminoacetic ester of formula I (R1 and R2 are 1W4C alkyl), e.g. methyl methoxyiminoacetate or ethyl methoxyiminoacetate, is reacted with an aromatic amine of formula II (R3 is 1W4C alkyl, 1W4C fluoroalkyl, 1W4C alkoxyl or halogen; n is 0, 1, 2 or 3), e.g. aniline, toluidine or xylidine, in the presence or absence of an inert organic solvent, e.g. methanol or ethanol, at 20W 150°C, and the resultant product is then hydrolyzed under neutral or alkaline conditions to afford the aimed compound.
