Versuchsvorschrift

To a solution of 4-fluoro-2-hydroxybenzoic acid ethyl ester (3.5 g) in dichloromethane (30 ml) were added N,N-diisopropylethylamine (5.0 g) and (chloromethyl)methyl ether (2.3 g) at 0° C., and this reaction mixture was stirred at room temperature overnight. This reaction mixture was poured into water, and the resulting mixture was extracted with ethyl acetate. The organic layer was washed with water and brine, and dried over anhydrous magnesium sulfate. The solvent was removed under reduced pressure. The residue was purified by column chromatography on silica gel (eluent: n-hexane/ethyl acetate) to give the title compound (2.8 g).
