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.
