実験手順: A suspension of 7-bromo-4-chloro-3-nitro[1,5]naphthyridine (54.42 g, 188.6 mmol) in chloroform (820 mL) was cooled to 0° C., and triethylamine (105 mL, 755 mmol) was added. A solution of 1-(aminomethyl)cyclopentanol (28.25 g, 245.2 mmol) in chloroform (272 mL) was added slowly over a period of 15 minutes. The reaction was allowed to warm to room temperature and stirred for 30 minutes. The solution was washed sequentially with water (500 mL) and saturated aqueous sodium bicarbonate (750 mL), dried over sodium sulfate, filtered, and concentrated under reduced pressure to provide 1-{[(7-bromo-3-nitro[1,5]naphthyridin-4-yl)amino]methyl}cyclopentanol. to warm to room temperature The solution was washed sequentially with water (500 mL) and saturated aqueous sodium bicarbonate (750 mL) dried over sodium sulfate filtered concentrated under reduced pressure

実験手順: To a solution of 1-(aminomethyl)cyclopentanol (approximately 55.2 mmol, prepared as described above) in dichloromethane (280 mL) was added triethylamine (7.76 mL, 55.7 mmol) and 4-chloro-3-nitroquinoline (9.22 g, 44.3 mmol). The mixture was allowed to stand at room temperature over the weekend. A solid formed that was isolated by filtration. Two more crops of solid were isolated from the mother liquor. The yellow solid was stirred in water and filtered. The solid was washed with water multiple times and was dried under vacuum with heat to give 8.29 g of 1-{[(3-nitroquinolin-4-yl)amino]methyl}cyclopentanol as yellow crystals. to stand at room temperature over the weekend A solid formed that was isolated by filtration Two more crops of solid were isolated from the mother liquor filtered The solid was washed with water multiple times was dried under vacuum with heat
