実験手順

Acetyl chloride (180 μL, 2.53 mmol) was added to a stirred solution of N-{2-[4-amino-7-[(6-aminohexyl)oxy]-2-(ethoxymethyl)-1H-imidazo[4,5-c]quinolin-1-yl]-1,1-dimethylethyl}-N′-isopropylurea (prepared as described in Parts A-H of Example 369, 1.18 g, 2.30 mmol) and triethylamine (0.64 mL, 4.60 mmol) in dichloromethane (100 mL) at 0° C. After approximately 20 minutes, the solution was allowed to warm to room temperature and was stirred overnight. The solution was transferred to a separatory funnel and washed with water (2×). The organic layer was dried over sodium sulfate, filtered, and concentrated under reduced pressure. The crude product was purified by flash chromatography (silica gel, elution with 10% methanol in dichloromethane) to yield 0.34 g of N-(6-{[4-amino-2-(ethoxymethyl)-1-(2-{[(isopropylamino)carbonyl]amino}-2-methylpropyl)-1H-imidazo[4,5-c]quinolin-7-yl]oxy}hexyl)acetamide as a tan solid, mp 90-110° C.
