実験手順
To a solution of 2-fluorophenol (10.35 g, 9.2 mmol) and tert-butyldimethylsilyl chloride (101 mmol) in DMF (180 ml) was added imidazole (7.54 g, 110 mmol) in one portion. After stirring for 3 h the reaction mixture was poured into water (300 ml) and extracted with diethyl ether (3×100 ml). The combined extracts were washed with 10% aqueous citric acid (100 ml), brine (100 ml), dried (MgSO4) and concentrated under reduced pressure to afford title compound (20.63 g, quant.) as a colorless liquid.
