Versuchsvorschrift

Triethylamine (1.77 mL, 12.7 mmol) was added to a solution of N1-(2-chloro-3-nitroquinolin-4-yl)-2-methylpropane-1,2-diamine (2.5 g, 8.5 mmol) in dichloromethane (25 mL), and the resulting solution was cooled to 0° C. and stirred for five minutes. Methanesulfonyl chloride (1.07 g, 9.33 mmol) was added in portions over a period of five minutes, and the reaction was allowed to warm to ambient temperature and stirred overnight. An analysis by high-performance liquid chromatography (HPLC) indicated the reaction was incomplete, and additional methanesulfonyl chloride (0.5 equivalent) was added. The reaction was stirred for two hours and again determined to be incomplete. Additional methanesulfonyl chloride (0.5 equivalent) and triethylamine (1.5 equivalents) were added, and the reaction was stirred for two hours and then diluted with dichloromethane. The resulting solution was washed twice with brine and twice with saturated aqueous sodium bicarbonate, dried over magnesium sulfate, filtered, and concentrated under reduced pressure to provide 3.1 g of N-{2-[(2-chloro-3-nitroquinolin-4-yl)amino]-1,1-dimethylethyl}methanesulfonamide as a yellow solid.
