Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Hydrochloric Acid | HCID 313 | — |
| Reactant | N-[2-Oxo-8-(piperazin-1-yl)-2H-1-benzopyran-3-yl]acetamide | HCID 59427368 | — |
| Product | 3-amino-8-(1-piperazinyl)-2H-1-benzopyran-2-one | HCID 11150964 | — |
Reaction Steps
Step 5 was the hydrolysis of the amide function of N-(8-(1-piperazinyl)-2-oxo-2H-1-benzopyran-3-yl-)acetamide (5*) using hydrochloric acid. This resulted in the trihydrochloric acid salt of 3-amino-8-(1-piperazinyl)-2H-1-benzopyran-2-one (6*).
