反応手順

To 3,4-diethoxybenzyl alcohol (736 mg) dissolved in toluene (10 ml) were added pyridine (one drop) and thionyl chloride (0.41 ml), and the resulting mixture was stirred at room temperature for 20 minutes. The reaction mixture was diluted with ethyl acetate and the resulting mixture was washed with water, an aqueous saturated solution of sodium hydrogen carbonate and an aqueous saturated solution of sodium chloride, and was dried with anhydrous magnesium sulfate. The resulting organic layer was evaporated under reduced pressure to remove the solvent to obtain 3,4-diethoxybenzyl chloride (802 mg) as an oil.
