Versuchsvorschrift
To a stirring solution of 2,6-dimethoxy-phenol (2 g, 12.98 mmol) in CCl4 (70 mL) at −10° C. was added bromine (2.07 g, 12.98 mmol) and stirred for 2 h. The reaction mixture was diluted with CCl4, washed with water and the combined CCl4 layers were washed with brine, dried over anhydrous sodium sulphate and concentrated under reduced pressure to afford 3-Bromo-2,6-dimethoxy-phenol as a solid (2 g, 66%).
