Procedure
Methoxypropionyl chloride (4.85 g, 39.8 mmol) was added dropwise over a period of ten minutes to a solution of ethyl 6-(3-aminoquinolin-4-ylamino)hexanoate (10.0 g, 33.2 mmol, prepared as described in Part A of Example 8) in dichloromethane (200 mL). The reaction was stirred for one hour at ambient temperature and then concentrated under reduced pressure. Triethylamine (18.49 g, 132.7 mmol) and ethanol (200 mL) were added, and the resulting solution was heated at reflux for three hours. The solvent was removed under reduced pressure. Dichloromethane (75 mL) was added, and the resulting solution was washed with saturated aqueous sodium bicarbonate, dried over magnesium sulfate, filtered, and concentrated under reduced pressure to provide 12.05 g of ethyl 6-[2-(2-methoxyethyl)-1H-imidazo[4,5-c]quinolin-1-yl]hexanoate as a dark oil.
