실험 절차

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 d at rt, 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 to a solid that was crystallized from isopropanol. The resulting crystals were combined with the solid that was isolated from the extraction and the mixture was triturated with hot isopropanol. The solid was isolated by filtration, washed with diethyl ether, and air dried to yield 1-{[(3-nitroquinolin-4-yl)amino]methyl}cyclobutanol as yellow crystals. (12.83 g, 75%).
