| Reactant | Hydrochloric Acid | HCID 313 | — |
| Reactant | 3-acetyl-8-methoxy-7-sulfamoyl-2,3,4,5-tetrahydro-1H-3-benzazepine | HCID 13853351 | — |
| Product | 8-methoxy-7-sulfamoyl-2,3,4,5-tetrahydro-1H-3-benzazepine hydrochloride | HCID 21242897 | — |
Reaction Steps
The sulfonamide (2.3 g, 0.007 m) was suspended in 3N hydrochloric acid and heated to reflux for 16 hours. The mixture was concentrated in vacuo and the residue crystallized from methanol to give 8-methoxy-7-sulfamoyl-2,3,4,5-tetrahydro-1H-3-benzazepine hydrochloride, m.p. 270°-274°.
