Versuchsvorschrift

3.0 g (10.23 mmol) of [4-(benzyloxy)-3-bromophenyl]methanol (Example I) are initially charged in 30 ml of DMF. At room temperature, 1.39 g (12.28 mmol) of 1H-imidazole (60% pure) and 2.01 g (13.3 mmol) of tert-butyl(chloro)dimethylsilane are added. The reaction mixture is stirred at room temperature overnight. Water is then added, and the mixture is extracted three times with diethyl ether. The combined organic phases are washed three times with water and once with saturated sodium chloride solution. The organic phase is dried with sodium sulphate and the solvent is removed under reduced pressure. This gives 4.02 g (86% of theory) of {[4-(benzyloxy)-3-bromobenzyl]oxy}(tert-butyl)dimethylsilane.
