3.59 g (19.08 mmol) of N-(tert-butoxycarbonyl)-1,4-diaminobutane was dissolved in 70 ml of triethylamine and 3.79 g (18.17 mmol) of 4-chloro-3-nitroquinoline was added thereto. The resulting mixture was heated at 70° C. and stirred for 4 hours. After the reaction mixture was concentrated under reduced pressure, the residue was dissolved in chloroform, washed with water, and dried (MgSO4). The solvent was distilled off under reduced pressure. The resulting residue was triturated with diethel ether and collected by filtration to obtain 5.77 g (16.01 mmol) of 4-[4-(tert-butoxycarbonylamino)butylamino]-3-nitroquinoline shown below as a yellow solid.
