Procedure

A solution of sodium hydroxide (1.66 g, 41.7 mmol) in water (15 mL) was added to a solution of ethyl 6-(1H-imidazo[4,5-c]quinolin-1-yl)hexanoate (10.0 g, 32.1 mmol, prepared in Part A of Example 10) in ethanol (75 mL), and the reaction was stirred at ambient temperature for two hours and then concentrated under reduced pressure. The residue was diluted with water and adjusted to pH 5 with the addition of 10% hydrochloric acid. The mixture was extracted with dichloromethane, and the combined extracts were dried over magnesium sulfate, filtered, and concentrated under reduced pressure to provide 2.5 g of 6-(1H-imidazo[4,5-c]quinolin-1-yl)hexanoic acid.
