Procedure

3.3 g of 3-(2'-chloro-4'-trifluoromethylphenoxy)phenylacetic acid was dissolved in 30 ml of dichloromethane, and the resulting solution was cooled to below 10° C. on the water bath. Then, 2.1 g of N,N'-dicyclohexylcarbodiimide (DCC) was added, followed by addition of 0.8 g of 2-propanethiol. The reaction was allowed to proceed at room temperature for about 6 hours. After completion of the reaction, the formed solid substance was filtered off, and the filtrate was subjected to evaporation-removal of the solvent under reduced pressure to obtain a crude product. The thus obtained crude product was subjected to purification by the silica gel column chromatography (elution was performed by using a mixed solvent of toluene and n-hexane). As a result, there was obtained 1.6 g of S-1-methylethyl 3-(2'-chloro-4'-trifluoromethylphenoxy)-phenylthioacetate.
