Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Ammonium Hydroxide | HCID 14923 | — |
| Reactant | 4-Acetyl-6-methoxy-1H-2-benzopyran-1,3(4H)-dione | HCID 57893130 | — |
| Product | 6-Methoxy-3-methylisoquinolin-1(2H)-one | HCID 12327060 | 74% |
Reaction Steps
The cyclic anhydride of step 1 (405 mg; 1.73 mmol) was dissolved in aqueous ammonium hydroxide, and heated at reflux for 1.5 hours. The mixture was cooled to room temperature and the solid was filtered then dried overnight to give 270 mg (74%) of 6-methoxy-3-methylisoquinolin-1(2H)-one.
