A modification of the method described in Part E of Example 1 was used to treat 7-benzyloxy-4-chloro-3-nitroquinoline (14.4 g, 45.8 mmol) with N-(4-aminobutyl)methanesulfonamide hydrochloride (10.2 g, 50.4 mmol) and triethylamine (19.2 mL, 137 mmol). The reaction mixture was concentrated under reduced pressure, and the residue was triturated with water while heating at reflux. The resulting solid was isolated by filtration, washed with water and diethyl ether (2×100 mL), and dried under high vacuum to provide 16.8 g of N-[4-(3-nitro-7-benzyloxyquinolin-4-ylamino)butyl]methanesulfonamide as a yellow powder.
