참여 물질

반응 단계

To (E)-2-(2-bromomethylphenyl)-2-methoxyimino-N-methylacetamide (0.72 g, 2.5 mmol), added were dry DMF (5.0 ml), 2,5-dimethylphenol (0.46 g, 3.75 mmol) and potassium carbonate (0.69 g, 5.0 mmol), and the reaction mixture was stirred at room temperature for 4 hours. Then, water (100 ml) was added to the reaction mixture which was then extracted with ethyl acetate (100 ml). The extract was washed with water (100 ml), dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was purified by silica gel chromatography (ethyl acetate/n-hexane) to give (E)-2-[2-(2,5-dimethylphenoxymethyl)phenyl]-2-methoxyimino-N-methylacetamide (0.57 g) as colorless crystals (yield, 69.8%).
