실험 절차

7-Bromo-4-chloro-3-nitroquinoline (11.00 g, 38.26 mmol) was reacted with (S)-2,2-dimethyl-[1,3]dioxolane-4-methanamine (5.81 g, 57.4 mmol) according to the method described in Part A of Examples 125-135. When the reaction was complete, it was concentrated under reduced pressure, and the residue was stirred with water (100 mL). The resulting solid was isolated by filtration, mixed twice with ethanol and concentrated under reduced pressure. The solid was then triturated with diethyl ether, isolated by filtration, and dissolved in dichloromethane. An insoluble impurity was removed by filtration, and the filtrate was concentrated under reduced pressure to provide 14.05 g of (S)-(7-bromo-3-nitroquinolin-4-yl)-(2,2-dimethyl-1,3-dioxolan-4-ylmethyl)amine as a yellow solid.
