摘要:
A process for producing an α-hydroxyiminophenylacetonitrile represented by general formula [II], (wherein R¹, R², R³ and Z are each as defined in the specification) by reacting a crude nitrile containing a phenylacetonitrile represented by general formula [I], (wherein R¹, R², R³ and Z are each as defined in the specification) with an alkyl nitrite in the presence of a base, extracting the reaction mixture with water, and neutralizing the separated water layer with an acid. This process enables target α-hydroxyiminophenylacetonitriles to be readily produced in a highly pure form in high yield by extracting the reaction mass with water and neutralizing the separated water layer with an acid.
