실험 절차

Under a nitrogen atmosphere, thionyl chloride (1.7 mL, 23 mmol) was added to a mixture of 5-{[6-(benzyloxy)-3-nitroquinolin-4-yl]amino}pentan-1-ol (5.95 g, 15.6 mmol) and anhydrous dichloromethane (78 mL). The reaction became homogeneous and was heated at reflux for 1.5 hours, at which time a yellow precipitate formed. The volatiles were removed under reduced pressure, and the residue was partitioned between dilute aqueous sodium carbonate (100 mL) and dichloromethane (150 mL). The aqueous layer was washed with dichloromethane (50 mL), and the combined organic solutions were washed with brine (50 mL), dried over sodium sulfate, filtered, and concentrated under reduced pressure to provide 6.24 g of 6-benzyloxy-N-(5-chloropentyl)-3-nitroquinolin-4-amine as a yellow oil.
