Procedure

6,6′-bis-bromomethyl-2,4,2′,4′-tetramethoxy-biphenyl (685 mg) was dissolved in DCM (3.0 mL), and 1M BBr3 in DCM (16.4 mL) was slowly added. After stirring for 2 days, the mixture was poured on to ice and concentrated. The crude material was used for the next step without a further purification.
