Procedure
Ethyl 4-(2-chloro-6-formylphenylthio)butyrate was synthesized from 2,3-dichlorobenzaldehyde and ethyl 4-mercaptobutyrate in the same manner as Example 2. After column chromatography, vacuum concentration yielded ethyl 4-(2-chloro-6-formylpehylthio)butyrate (Yield 70%) as a yellow oily matter.
