実験手順

To a solution of 4-bromophenol (16.4 g, 0.1 mole) in CH2Cl2 (300 mL) was added t-butyldiphenylsilyl chloride (29 g, 0.1 mole), Et3N (20 g, 0.2 mole) and 4-dimethylaminopyridine (DMAP) (1 g). The solution was stirred at RT for 2 days, quenched with H2O (1 L) and extracted with ether (2 L). The ether extracts were dried and evaporated. Flash chromatography of the residue using 5% ethyl acetate in hexane afforded the title compound which was used as such for the next step.
