Reaction Steps

Under a nitrogen atmosphere, a solution of (2-amino-2-methylpropyl)(7-benzyloxy-3-nitroquinolin-4-yl)amine (6.5 g, 17.5 mmol), prepared in Part A of Example 45, in dichloromethane (200 mL) was cooled to 0° C.; triethylamine (4.87 mL, 35.0 mmol) and acetyl chloride (1.37 mL, 19.2 mmol) were sequentially added. The reaction was stirred at 0° C. for 30 minutes, allowed to warm to ambient temperature, and stirred for three hours. The reaction was washed with saturated aqueous sodium bicarbonate (2×) and brine, dried over sodium sulfate, filtered, and concentrated under reduced pressure to provide N-[1,1-dimethyl-2-(3-nitro-7-benzyloxyquinolin-4-ylamino)ethyl]acetamide as a yellow powder.
