To a solution of 2-chlorophenol (2.06 mL, 19.9 mmol) in DMF (40 mL) is added potassium carbonate (3.03 g, 21.9 mmol) and ethyl bromoacetate (2.3 mL, 20.7 mmol), and the mixture is stirred at 80° C. for 18 h. Et2O is added, and the mixture is washed with water, brine, dried (MgSO4), and filtered. The filtrate is evaporated, and the residue is purified by chromatography in silica gel; elution with EtOAc:dichloromethane:hexane (10:5:85) gives 4.17 g of the product 465. 1H NMR (CDCl3) δ 7.38 (d, 1H), 7.21 (t, 1H), 6.92 (t, 1H), 6.84 (d, 1H), 4.70 (s, 2H), 4.27 (q, 2H), 1.29 (t, 3H); MS: m/z 215, 217 (M++1).
