Versuchsvorschrift

To a solution of 1-bromo-2-methoxy-4-phenoxy-benzene (100.00 mg, 0.35 mmol) in DCM (5 mL) was slowly added boron tribromide (0.16 mL, 1.53 mmol) at −20° C. The reaction was stirred at that temperature for 2 h. The reaction mixture was concentrated in vacuo and dried on the pump. The crude reaction mixture was used for next step without further purification.
