Versuchsvorschrift

To a solution of methyl(3-bromo-2-hydroxyphenyl)acetate (18.7 g, 76.3 mmol) in 200 mL of DMF was added K2CO3 (52.7 g, 382 mmol), MeI (14.0 mL, 229 mmol). The mixture was stirred at 50° C. for 3 hours. The reaction solution was diluted with EtOAc and water. The organic layer was dried over anhydrous sodium sulfate and concentrated. The residue was purified column chromatography to give methyl[3-bromo-2-(methyloxy)phenyl]acetate.
