2-(3-溴苯氧基)乙氧基-叔-丁基-二甲基硅烷

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To a solution of 2-(3-Bromo-phenoxy)-ethanol (2.0 g, 9.2 mol) in dichloromethane (15 mL) at ice water bath temperature was added (1.25 g, 1.84 mmol) imidazole followed by the addition of TBSCl (1.67 g, 11 mmol) under nitrogen protection. TLC showed reaction was complete in 1 h. The reaction mixture was filtered. The filtrate was washed with water and dried over Na2SO4. The crude product was purified by column chromatography eluted with hexanes/ethyl acetate to afford titled product as a light color oil (2.65 g, 87%). reaction The reaction mixture was filtered The filtrate was washed with water dried over Na2SO4 The crude product was purified by column chromatography eluted with hexanes/ethyl acetate
