실험 절차
To a stirred solution of (±)-spiro[imidazolidine-4,2′-indane]-2,5-dione (1.0 g, 4.97 mmol) in 48% HBr (30 mL) was added Br2 (3.1 g, 19.9 mmol) and the reaction mixture was allowed to stir at ambient temperature for 4 days. The reaction was poured onto ice (30 g) and H2O (10 mL) and the solid precipitate filtered off, washed with H2O (4×20 mL), and dried in vacuo to give the title compound as a light brown solid. MS: m/z=282 (M+1).
