Reaktionsschritte
To a solution of 4-fluoro-2-hydroxybenzoic acid (3.0 g) in N,N-dimethylformamide (5 mL) were added sodium hydride (60% 1.0 g) and (chloromethyl)methyl ether (2.1 g) at room temperature, and this mixture was stirred for 48 hours at the same temperature. This reaction mixture was poured into 2 mol/L hydrochloric acid and the resulting mixture was extracted with ethyl acetate. The organic layer was washed with 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 (0.22 g).
