Procedure
A mixture of 2-(3-chloro-2-iodophenyl)acetic acid (3.2 g, 11 mmol) in 50 mL EtOH was treated with 2 mL con. H2SO4, and refluxed for 2 hours. The mixture was cooled to room temperature, diluted with 200 mL EtOAc, washed with water (3×50 mL), saturated NaCl (20 mL), dried over anhydrous sodium sulfate and concentrated. The concentrate was purified by column chromatography (10-20% EtOAc/hexane) to give 3.62 g pale yellow oil. MS m/e: (M+H)+ 325.
