(57) [Summary] (Modified) [Structure] In the presence of a phase transfer catalyst, in a mixed solvent of a hydrocarbon solvent and water, a compound of the general formula [I] A general formula [III] characterized by reacting an alkali metal salt of an α-hydroxyiminophenylacetonitrile derivative represented by the formula with a dialkylsulfuric acid represented by the general formula [II] (R 3 ) 2 SO 4 [II] A method for producing an α-alkoxyiminophenylacetonitrile derivative represented by: (In the formula, R 1 and R 2 are the same or different, and are an alkyl group having 1 to 5 carbon atoms and 2 to 4 carbon atoms. Alkenyl group, hydrogen atom, etc., Y is -O-, -S-, In —NCH 3 — and the like, A represents a hydrogen atom, an alkali metal, or an alkaline earth metal. R 3 represents an alkyl group. ) [Effect] Suppress the production of by-product nitrone derivative, A compound having a highly pure alkoxyimino group can be produced in high yield. |
