Versuchsvorschrift

(3-Chloro-phenyl)-acetic acid (6.03 g, 0.03 mol) was dissolved in ethanol (37.7 mL) and treated with a catalytic amount of sulfuric acid. The reaction mixture was refluxed for 12 h. The reaction was concentrated in vacuo. Flash chromatography (Merck Silica gel 60, 230-400 mesh, 50/50 hexanes/ethyl acetate) afforded (3-chloro-phenyl)-acetic acid ethyl ester (6.10 g, 86.8%) as a clear oil: EI-HRMS m/e calcd for C10H11ClO2 (M+) 198.0448, found 198.0442.
