Glutaric anhydride → 5-[(2-Acetylphenyl)amino]-5-oxopentanoic acid
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Glutaric anhydride | HCID 7940 | — |
| Reactant | 2'-Aminoacetophenone | HCID 11086 | — |
| Solvent | Benzene | HCID 241 | — |
| Product | 5-[(2-Acetylphenyl)amino]-5-oxopentanoic acid | HCID 18381917 | 66.8% |
Reaction Steps
1-(2-aminophenyl)ethane-1-one (4.00 g) and glutaric anhydride (4.10 g) were dissolved in benzene (30 ml) and the solution was heated to reflux for 3.5 hours, followed by concentration of the mixture. The residue was recrystallized from ethyl acetate to obtain 4.93 g of 4-(N-(2-acetylphenyl)carbamoyl)butanoic acid as colorless plate-like crystals. Yield: 66%.
