Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 6-Bromo-3,4-dimethoxybenzaldehyde | HCID 79351 | — |
| Reactant | Ethyl 4-sulfanylbutanoate | HCID 271824 | — |
| Product | Ethyl 4-(3,4-dimethoxy-6-formylphenylthio)butyrate | HCID 18533384 | 27% |
Reaction Steps
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.
