Reaction Conditions

Reaction Steps

85% Potassium hydroxide (0.79 g, 12.0 mmol) and toluene (20 ml) were added to (E)-2-(2-phenoxyphenyl)-2-methoxyiminoacetamide (2.70 g, 10.0 mmol) and dissolved by heating to 50° C. After 10 minutes, the solution was concentrated under reduced pressure. Toluene (20 ml) was added to the residue, and dimethyl sulfate (1.32 ml, 14.0 mmol) was added dropwise under ice-cooling and reacted at room temperature for 1 hour. After completion of the reaction, water (100 ml) was added. The mixture was extracted with ether (150 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 (E)-2-(2-phenoxyphenyl)-2-methoxyimino-N-methylacetamide (2.33 g, Yield: 82.1%).
