Versuchsvorschrift

A mixture of 8-(aminomethyl)quinoline (14 mg, 0.088 mmol), (±)-6′-carboxy-3′,4′-dihydro-1′H-spiro[imidazolidine-4,2′-naphthalene]-2,5-dione (described in Intermediate 1) (15 mg, 0.058 mmol), EDC (22 mg, 0.115 mmol), and HOBT (13 mg, 0.088 mmol) was stirred in DMF (0.8 mL) at ambient temperature for 18 h. The crude mixture was purified directly 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 tan solid. MS: m/z=401 (M+1). HRMS: m/z=401.1584; calculated m/z=401.1608 for C23H21N4O3.
