Procedure
85% Potassium hydroxide (1.19 g, 0.018 mol) and toluene (30 ml) were added to 2-phenoxy-α-methoxyiminobenzyl cyanide (E/Z=7/93)(3.78 g, 0.015 mmol). The mixture was stirred at 80° C. for 2.5 hours. After completion of the reaction, water (100 ml) was added. The mixture was neutralized with conc. hydrochloric acid, extracted with ether (100 ml), dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The resulting residue was purified by silica gel chromatography (ethyl acetate/n-hexane) to give 2-(2-phenoxyphenyl)-2-methoxyiminoacetamide (3.66 g, Yield: 90.3%, E/Z=6/94).
