Water → 4-methoxy-2-(methoxymethoxy)benzaldehyde

Participants

Reaction Steps

A solution of 4-methoxysalicylaldehyde (7.54 g) and N-ethyl diisopropylamine (17 ml) in dichloromethane (250 ml) was cooled to 0° C., to which was added dropwise chloromethyl methyl ether (6.0 ml). The mixture was then warmed up to room temperature, which was stirred overnight. To the reaction mixture was added water to quench the reaction, which was subjected to extraction with chloroform. The organic layer was dried (anhydrous magnesium sulfate), then the solvent was distilled off under reduced pressure. The residue was purified by means of a silica gel column chromatography (eluted with ethyl acetate/hexane) to give 4-methoxy-2-methoxymethoxy benzaldehyde (8.82 g) (Compound B-4), whose physico-chemical properties are shown in Table 5.
