Reaction Steps

Triethylamine (58.9 mL, 422.4 mmol, 1.5 eq) and tert-butyl N-(2-aminoethyl) carbamate (54.1 g, 337.9 mmol, 1.2 eq) were added sequentially to a solution of 7-benzyloxy-4-chloro-3-nitroquinoline (88.63 g, 281.6 mmol) in DMF (800 mL) and stirred for 4 hours at ambient temperature. The crude reaction mixture was poured into hot water with continuous stirring to afford bright a yellow precipitate. The yellow solid was filtered and dried under reduced pressure at 65° C. to afford 123.65 g of tert-butyl 2-[(7-benzyloxy-3-nitroquinolin-4-yl)amino]ethylcarbamate.
