Reaction Steps
A solution of [2-(3-fluoro-phenyl)-ethoxy]-acetic acid (1.20 g, 6.05 mmol), EDCI (1.28 g, 6.66 mmol), HOBt (0.90 g, 6.66 mmol) and DIPEA (1.56 ml, 9.08 mmol) in methanol (4 ml) was stirred at 0° C. for 2 hours. The reaction mixture was brought to dryness, dissolved in CH2Cl2 and washed twice with 1M NaOH and brine. The organic layers were dried over MgSO4, filtrated, the solvent was removed under reduced pressure and the residue was purified by column chromatography (silica gel, EtOAc/heptane, 1/4) to yield [2-(3-fluoro-phenyl)-ethoxy]-acetic acid methyl ester (1.20 g, 5.6 mmol; 93%) as colorless liquid. MS (m/e): 213.2 [M+H]+.
