To a stirred suspension of 65 mg of 2-chloro-N-(6-oxo-5,6-dihydro-phenanthridin-2-yl)-acetamide (XV) (0.23 mmol) in N,N-dimethylformamide (2 mL), 175 mg of (6-amino-hexyl)-carbamic acid tert-butyl ester hydrochloride (0.69 mmol) and 0.097 mL of triethylamine (0.69 mmol) were added. The reaction mixture was stirred at room temperature overnight, diluted with dichloromethane, and the resulting solution was washed first with water then with brine, dried over sodium sulfate and evaporated to dryness. The crude was purified by preparative HPLC on Waters X Terra RP 18 (19×250 mm, 5 □m) column. Mobile phase A was 0.05% ammonia/acetonitrile:95/5 and mobile phase B was acetonitrile/water:95/5. Gradient from 10 to 75% B in 15 min. Fractions containing the desired compound were dried, affording 50 mg (47% yield) of the title compound.
