Reaktionsschritte
TBSCl (18.7 g, 124.3 mmol), Et3N (14.08 g, 139.2 mmol) and DMAP (194.3 mg, 8.9 mmol) were dissolved in CH2Cl2 (120 mL) and the solution was cooled to 0-5° C. (3-Bromophenyl)methanol (18.5 g, 99.4 mmol) was added dropwise to the solution. After the addition of the (3-bromophenyl)methanol, the mixture was warmed to room temperature and stirred for 2 h. 5% HCl was added to the reaction mixture to adjust the pH=4-5. Then the organic phase was separated and the aqueous layer was extracted with CH2Cl2 (50 mL×2). The combined organic phases were washed with water and dried over Na2SO4. After removing the solvent, 28.5 g of {[(3-bromophenyl)methyl]oxy}(1,1-dimethylethyl)dimethylsilane was obtained (Yield: 95.1%).
