Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Hydrochloric Acid | HCID 313 | — |
| Reactant | Ethyl 2-cyano-4-oxo-4-phenylbutanoate | HCID 15633746 | — |
| Solvent | Tetrahydrofuran | HCID 8028 | — |
| Product | HCID 14937509 | HCID 14937509 | 79% |
Reaction Steps
To a solution (60 mL) of ethyl 2-cyano-4-oxo-4-phenylbutanoate (5.0 g) in tetrahydrofuran was blown in hydrogen chloride (28 g) under ice-cooling, and the mixture was stirred at room temperature for 3 hr. Then, nitrogen was blown in to remove hydrogen chloride. The reaction mixture was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography (eluent: hexane-ethyl acetate=6:1) to give the title compound as a pale-yellow solid (yield 4.24 g, 79%).
