Procedure

To a suspension of 2,4-dihydroxybenzaldehyde (0.83 g) and cesium carbonate (1.7 g) in acetonitrile (30 mL) was added chloromethyl methyl ether (0.55 mL), and the mixture was stirred at room temperature for 30 minutes. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate, and the solvent was removed under reduced pressure. The residue was purified by column chromatography on silica gel (eluent: hexane/ethyl acetate=4/1) to give 2-hydroxy-4-(methoxymethyloxy)benzaldehyde (0.84 g).
