反応手順

A solution of 2,4-dichloro-3-nitroquinoline (11.4 g, 47.1 mmol) in DMF (200 mL) was cooled to 0° C. Triethylamine (19.6 mL, 0.141 mol) and 1-(N-Boc-aminomethyl)-4-(aminomethyl)benzene (13.3 g, 56.5 mmol) were sequentially added, and the reaction was stirred for one hour and cooled again to 0° C. Water (300 mL) was added, and the mixture was stirred for 30 minutes at 0° C. and then extracted with dichloromethane. The dichloromethane fraction was concentrated under reduced pressure to provide 20 g of tert-butyl 4-{[(2-chloro-3-nitroquinolin-4-yl)amino]methyl}benzylcarbamate as a red oil.
