실험 절차

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 0.1 N 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.
