実験手順

3-Chlorophenol (3.09 g, 0.024 mol), dimethyl-formamide (20 ml) and potassium carbonate (4.15 g, 0.03 mol) were added to 2-chloromethyl-α-methoxyiminobenzyl chloride (4.36 g, 0.02 mol), and the mixture was stirred at room temperature for 4 days. After completion of the reaction, ether (250 ml) was added, and the mixture was washed with brine (200 ml) twice. The ether layer was dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was purified by silica gel chromatography (ethyl acetate/n-hexane) to give 2-(3-chlorophenoxymethyl)-α-methoxyiminobenzyl chloride (5.66 g, 91.2%) as a colorless oil.
