実験手順

To a solution of 5.00 g (26.8 mmol) of methyl 3-chloro-4-hydroxybenzoate dissolved in 40 mL of CH2Cl2 was added 6.55 g (53.6 mmol) of 4-dimethylaminopyridine, 4.85 g (32.2 mmol) of tert-butyldimethylchlorosilane and the mixture was stirred at room temperature for 3.5 hours. The reaction mixture was filtered, diluted with ethyl acetate, washed with 0.1N HCl, saturated NaHCO3, and brine. The product layer was then dried (MgSO4), filtered and evaporated in vacuo to afford 8.05 g (100%) of the title compound.
