Triethylamine (8.93 mL, 64.1 mmol) was added to a solution of 7-benzyloxy-4-chloro-3-nitroquinoline (13.45 g, 42.7 mmol), prepared in Parts A-D of Example 1, in dichloromethane (250 mL). 2-Phenoxyethylamine (6.15 mL, 47.0 mmol) was added dropwise over a period of ten minutes, and the reaction mixture was stirred for three hours at ambient temperature. Distilled water (200 mL) was added to the solution, and the aqueous layer was washed with dichloromethane (2×200 mL). The combined organic solutions were dried over magnesium sulfate, filtered, and concentrated under reduced pressure to provide a solid. The solid was washed with hexanes, isolated by filtration, and dried under reduced pressure to provide 17.14 g of (7-benzyloxy-3-nitroquinolin-4-yl)-(2-phenoxyethyl)amine as a yellow solid.
