Procedure

To a stirred solution of 50 mg (0.23 mmol) (±)-5′-amino-spiro[imidazolidine-4,2′-indane]-2,5-dione (described in Intermediate 6) in THF (3 mL) was added 1-naphthalenesulfonyl chloride (53 mg, 0.24 mmol) and triethylamine (0.034 mL, 0.24 mmol). After 30 min the reaction mixture was concentrated to dryness. The residue was dissolved in DMF and purified by HPLC using a reversed phase C18 column and eluting with a gradient of H2O:CH3CN:CF3CO2H—90:10:0.1 to 5:95:0.1. Lyophilization provided the title compound as a white solid. MS: m/z=408 (M+1). HRMS: m/z=408.1019; calculated m/z=408.1013 for C21H17N3O4S.
