Versuchsvorschrift
Ethyl 4-(4-(4-ethoxyphenyl)-2-formylphenylthio)butyrate was synthesized from 5-(4-ethoxyphenyl)-2-fluorobenzaldehyde and ethyl 4-mercaptobutyrate in the same manner as Example 2. After concentration of an extracted solution, crystallization from hexane/isopropyl ether yielded ethyl 4-(4-(4-ethoxyphenyl)-2-formylphenylthio)butyrate (Yield 73%) as yellow crystals.
