Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Beta-Alanine | HCID 239 | — |
| Reactant | Phthalic Anhydride | HCID 6811 | — |
| Product | 2-[(2-Carboxyethyl)carbamoyl]benzoic acid | HCID 14974020 | 90% |
Reaction Steps
25 grams (0.28 mole) of β-alanine and 41.6 grams (0.28 mole) of phthalic anhydride were heated at 150° C. while stirring for three hours and then cooled. On recrystallizing with ethyl acetate, N-phthalyl-β-alanine was obtained in 90% yield (55 grams).
