実験手順
5-[2-(Ethoxymethyl)-1H-imidazo[4,5-c]quinolin-1-yl]pentanamide (2.25 g, 6.89 mmol) was treated with mCPBA (2.77 g, 12.0 mmol), ammonium hydroxide (40 mL), and benzenesulfonyl chloride (1.71 mL, 13.4 mmol) according to the method described in Part D of Example 36. The crude product was purified by column chromatography on silica gel (eluting with dichloromethane:methanol in a gradient from 90:10 to 85:15). The resulting product was triturated with 10% aqueous sodium hydroxide, isolated by filtration, washed with water, and dried overnight in a vacuum oven to provide 0.752 g of 5-[4-amino-2-(ethoxymethyl)-1H-imidazo[4,5-c]quinolin-1-yl]pentanamide as a tan solid, mp 198-200° C.
