Imidazole → (4-Bromophenoxy)(tert-butyl)dimethylsilane

反応手順

4-Bromophenol (1.00 g) was dissolved in N,N-dimethylformamide (20 ml) to prepare a solution. Imidazole (0.95 g) and tert-butylchlorodimethylsilane (1.05 g) were added to the solution, and the mixture was stirred at room temperature overnight. Water was added to the reaction solution, and the mixture was extracted with ethyl acetate. The ethyl acetate layer was then washed with water and saturated brine and was dried over anhydrous sodium sulfate. The solvent was removed by distillation under the reduced pressure, and the residue was purified by column chromatography using chloroform to give (4-bromo-phenoxy)-tert-butyl-dimethyl-silane (1.586 g, yield 96%).
