実験手順

A solution of sodium hydroxide (2.23 g, 55.9 mmol) in water (100 mL) was added to a solution of ethyl 5-(2-propyl-1H-imidazo[4,5-c]quinolin-1-yl)pentanoate (14.6 g, 43.0 mmol) in ethanol (100 mL). The reaction mixture was stirred at room temperature overnight, then the ethanol was removed under reduced pressure. The remaining aqueous solution was washed with dichloromethane and adjusted to pH 5 with 10% aqueous hydrochloric acid. The aqueous layer was extracted with dichloromethane (2×). The later organic layers were combined, dried over magnesium sulfate, filtered, and concentrated to yield 11.5 g of 5-(2-propyl-1H-imidazo[4,5-c]quinolin-1-yl)pentanoic acid as yellow solid.
