Procedure

A solution of methyl 2-[2-(2,5-dimethylphenoxymethyl)phenyl]-2-hydroxyacetate (0.50 g, 1.6 mmol) in 1,2-dichloroethane (20 ml) was stirred at room temperature. Thionyl chloride (0.61 g, 5.1 mmol) was added thereto, and the mixture was heated under reflux overnight and concentrated under reduced pressure. The residue was purified by column chromatography on silica gel (n-hexane/ethyl acetate=97/3) to give the desired compound methyl 2-chloro-2-[2-(2,5-dimethylphenoxymethyl)phenyl]acetate (0.35 g, 66%) as an oil.
