Imidazole → [(3-Bromophenyl)methoxy](tert-butyl)diphenylsilane

Participants

Reaction Steps

A mixture of 3-bromobenzyl alcohol (15.0 g, 80 mmol), tert-butylchlorodiphenylsilane (22.9 mL, 88 mmol), imidazole (12.0 g, 176 mmol) and 75 mL of dimethylformamide was stirred at room temperature overnight. The reaction mixture was poured into cold water, extracted with diethyl ether, the extracts washed with water and brine, dried over sodium sulfate and evaporated. The resulting oil was purified by chromatography on silica gel with hexane to give 23.7 g (70%) of 3-bromobenzyl tert-butyldiphenylsilyl ether as a colorless oil.
