Procedure

A solution of 8.0 g (3-bromo-4-methoxy-phenyl)-{4-[(triisopropylsilyl)-ethynyl]-phenyl}-methanol and 5.7 mL triethylsilane in 80 mL dichloromethane is cooled in an ice bath. Then 6.5 mL trifluoroacetic acid are added dropwise, and the solution is stirred for 4 h in the cooling bath. The solution is diluted with dichloromethane and washed with aqueous sodium hydrogen carbonate solution. After drying over sodium sulfate the solvent is removed to give the product.
