tert-Butyldimethylsilyl chloride → HCID 131734205, compound

Participants

Reaction Steps

To a solution of benzyl (2-bromo-4-hydroxyphenyl)acetate (2.00 g) in dichloromethane (30.0 mL) were added tert-butyl (chloro)dimethylsilane (1.13 g) and N,N-dimethyl-4-aminopyridine (913 mg) under ice-cooling, followed by stirring for 2 hours under ice-cooling. The reaction mixture was diluted with water, followed by extraction with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane-ethyl acetate) to obtain benzyl (2-bromo-4-{[tert-butyl(dimethyl)silyl]oxy}phenyl)acetate (2.63 g).
