| Reactant | 1',3'-dihydrospiro[imidazolidine-4,2'-indene]-2,5-dione | HCID 279999 | — |
| Product | HCID 16638331 | HCID 16638331 | — |
Reaction Steps
A solution of (±)-spiro[imidazolidine-4,2′-indane]-2,5-dione (3.0 g, 14.8 mmol) in conc. nitric acid (33 mL) was stirred at ambient temperature for 1 h. The reaction was then poured onto crushed ice and the resultant solid was isolated by filtration. The crude material was recrystallized from ethanol to give the title compound as a yellow solid. MS: m/z=248 (M+1).
