Reaction Steps

Into a 200 ml four-necked flask equipped with a stirrer, a reflux condenser, a thermometer and a dropping funnel, 97 ml (1 mol) of carbon tetrachloride and 26.7 g (0.2 mol) of aluminum chloride were charged, and 19.3 g (0.1 mol) of 1-bromo-3,4-difluorobenzene was dropwise added under reflux. Thereafter, the mixture was reacted for 30 minutes. The reaction mixture was treated in the same manner as in Example 1 to obtain 21.1 g (yield: 68.1%) of 2-bromo-4,5-difluorobenzotrichloride.
