Chloroacetic Acid → 2-[2-(3-Fluorophenyl)ethoxy]acetic acid

Participants

Reaction Conditions

Reaction Steps

To a solution of 2-(3-fluoro-phenyl)-ethanol (4.0 g, 28.5 mmol) in DMF (60 ml) was added a 60% dispersion of sodium hydride in oil (2.40 g, 60 mmol). The suspension was heated to 60° C. for 0.75 hours. Chloroacetic acid (4.72 g, 50 mmol) was added dropwise. After 36 hours at 60° C. the brown reaction mixture was brought to dryness under reduced pressure, dissolved in EtOAc and washed with 1M HCl, water and brine. The organic layers were dried over MgSO4, filtrated, the solvent was removed under reduced pressure and the residue purified by column chromatography (silica gel, EtOAc/heptane, 3/1) to yield [2-(3-fluoro-phenyl)-ethoxy]-acetic acid (2.02 g, 18 mmol; 36%) as colorless liquid. MS (m/e): 197.4 [M−H]−.
