Reaction Steps

To a suspension of (±)-5′-nitro-spiro[imidazolidine-4,2′-indane]-2,5-dione (1.77 g, 7.16 mmol) in EtOAc (100 mL) and MeOH (100 mL) was added 10% Pd/C (400 mg) and the reaction stirred vigorously under hydrogen (ca. 1 atm). After 1 h, the catalyst was filtered off and the filtrate was concentrated to yield the title compound. MS: m/z=218 (M+1).
