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