反应详情

Salicylaldehyde (3 g) was slowly added to a N,N-dimethylformamide solution (50 mL) of sodium hydride (55%, 1.2 g) at 0° C. The mixture was stirred at the same temperature for 1 hour. Subsequently, chloromethylmethyl ether (2.9 g) was added thereto. After confirmation of the degree of reaction progress by TLC, the reaction was quenched with an aqueous solution of ammonium chloride. The organic layer was extracted with ethyl acetate and then was dried over anhydrous magnesium sulfate. The crude product obtained by concentrating the organic phase was purified by column chromatography to obtain 3.9 g (yield: 96%) of 2-methoxymethoxybenzaldehyde.
