Versuchsvorschrift
Ethyl 4-(4-bromo-2-formylphenylthio)butyrate was synthesized from 5-bromo-2-fluorobenzaldehyde and ethyl 4-mercaptobutyrate in the same manner as Example 2. After column chromatography, crystallization from hexane/isopropyl ether yielded ethyl 4-(4-bromo-2-formylphenylthio)butyrate (Yield 78%) as yellow crystals.
