実験手順: To a solution of 1-(aminomethyl)cyclobutanol (62.5 mmol) in dichloromethane (312 mL) was added triethylamine (8.71 mL, 62.5 mmol) and 4-chloro-3-nitroquinoline (13.04 g, 62.5 mmol). More triethylamine (3 mL) was added almost immediately. The reaction was stirred under N2 for 10 days at room temperature, then was diluted with dichloromethane and washed with 1 M aqueous NaOH. A solid formed and was isolated by filtration. The organic layer was washed with water and brine, dried over Na2SO4, filtered, and concentrated under reduced pressure to yield a solid that was crystallized from 2-propanol. The resulting crystals were combined with the solid that was isolated from the extraction and the mixture was triturated with hot 2-propanol. The solid was isolated by filtration, washed with diethyl ether, and air dried to yield 12.83 g of 1-{[(3-nitroquinolin-4-yl)amino]methyl}cyclobutanol as yellow crystals. washed with 1 M aqueous NaOH A solid formed was isolated by filtration The organic layer was washed with water and brine dried over Na2SO4 filtered concentrated under reduced pressure to yield a solid that was crystallized from 2-propanol that was isolated from the extraction the mixture was triturated with hot 2-propanol The solid was isolated by filtration washed with diethyl ether, and air dried

実験手順: A solution of 4-chloro-3-nitroquinoline (30.0 g, 144 mmol) in dichloromethane (350 mL) was cooled to 0° C. under a nitrogen atmosphere, and triethylamine (22.1 mL, 158 mmol) was added. A solution of 1-(aminomethyl)cyclobutanol (16.0 g, 158 mmol) in dichloromethane (130 mL) was then added over a period of one hour, followed by a rinse of dichloromethane (100 mL). The reaction was stirred at room temperature overnight. The solvent was removed under reduced pressure, and the residue was triturated in water (500 mL) and saturated aqueous sodium bicarbonate (200 mL) for two hours.
