Reaktionsschritte
Ethyl 4-(3,4-dimethoxy-6-formylphenylthio)butyrate was synthesized from 6-bromoveratraldehyde and ethyl 4-mercaptobutyrate in the same manner as Example 2. After vacuum concentration of an extracted solution, the residue was crystallized from isopropyl ether to yield ethyl 4-(3,4-dimethoxy-6-formylphenylthio)butyrate (Yield 27%) as slightly yellow crystals.
