실험 절차

To a solution of 2-chloro-4-fluorophenol (617, 7 g, 0.05 mol) in tetrahydrofuran (100 mL) was added sodium hydride (1.8 g, 95% dry powder, 0.071 mol) at room temperature over 15 minutes under an atmosphere of nitrogen. The reaction mixture was stirred at room temperature for 30 minutes. Benzyl bromide (10 g, 0.060 mol) was added slowly to the reaction mixture, then stirred at room temperature overnight. The reaction mixture was poured into ice water, extracted with ethyl acetate, washed with hydrochloric acid (10%), water, brine, and dried over magnesium sulfate. After removal of solvent, the residue was purified by silica gel column chromatography eluting with ethyl acetate in hexane to provide compound as a white solid (618, 7.6 g, 60%).
