Reaction Steps

2 ml of benzylamine was added to 70 mg (0.187 mmol) of 1-[4-(tert-butoxycarbonylamino)butyl]-4-chloro-1H-imidazo-[4,5-c]quinoline. The resulting mixture was heated at 150° C. and stirred for 3 hours. An excess amount of benzylamine was distilled off under reduced pressure and 1N hydrochloric acid and brine were added thereto. The resulting solution was extracted twice with methylene chloride. The organic phase was washed with a saturated sodium hydrogencarbonate aqueous solution and dried (Na2SO4). The solvent was then distilled off under reduced pressure. The residue was purified by silica gel column chromatography (chloroform:methanol=150:1 (v/v)) to obtain 79 mg (0.177 mmol) of 4-benzylamino-1-[4-(tert-butoxycarbonylamino)butyl]-1H-imidazo[4,5-c]quinoline shown below as white powder (mp: 151 to 153.5° C.). ##STR46## Its spectroscopic data are as follows: IR (KBr) cm-1 : 3380, 3310, 2930, 1680, 1595, 1540, 1245, 1160.
