Triethylamine (12.5 mL, 0.0889 mol) and 1-(N-Boc-aminomethyl)-3-(aminomethyl)benzene (17.71 g, 74.94 mmol) were sequentially added to a solution of 2,4-dichloro-3-nitroquinoline (18.2 g, 0.0750 mol) in DMF (90 mL), and the reaction was stirred at room temperature under nitrogen for 1.5 hours. The reaction was poured into water (2 L), and the suspension was stirred for 15 minutes. Most of the water was decanted away from the resulting precipitate, which was dissolved in ethyl acetate (600 mL). The ethyl acetate was separated from a small amount of remaining water and then removed under reduced pressure. The resulting solid was dried under vacuum to provide 38.24 g of tert-butyl 3-{[(2-chloro-3-nitroquinolin-4-yl)amino]methyl}benzylcarbamate as a sticky, amber solid.
