To α-hydroxyimino-2-phenoxyphenylacetonitrile (a mixture of E- and Z-isomers) (0.71 g, 0,003 mole) were added ethanol (3 ml), potassium hydroxide (0.40 g, 0.0072 mole) and water (3 ml). After completion of the reaction, methylene chloride (10 ml) and 10% hydrochloric acid were added to the reaction mixture, and the crystals of α-hydroxyimino-2-phenoxyphenylacetic acid precipitated were filtered off to obtain colorless crystals (0.47 g, yield: 60.9 %).
