実験手順

3-Chloroperoxybenzoic acid (60% pure, 0.283 g, 1.0 mmol) was added to a solution of N-[2-(ethoxymethyl)-1-(2-hydroxy-2-methylpropyl)-1H-imidazo[4,5-c]quinolin-8-yl]-2-methylpropanamide (0.380 g, 1.0 mmol) in chloroform (10 mL) and the reaction was stirred for 1 hour. The mixture was cooled in an ice bath and ammonium hydroxide (3 mL) was added. After 15 minutes of stirring, p-toluenesulfonyl chloride (0.190 g, 1.0 mmol) was added and the reaction mixture was stirred for 72 hours. The fractions were separated and the aqueous fraction was extracted with chloroform. The combined organic fractions were washed with brine and purified by chromatography using a HORIZON HPFC system (silica cartridge, eluting with a linear gradient of 2-20% CMA in chloroform). Recrystallization from acetonitrile provided 0.231 g of N-[4-amino-2-(ethoxymethyl)-1-(2-hydroxy-2-methylpropyl)-1H-imidazo[4,5-c]quinolin-8-yl]-2-methylpropanamide as an off-white solid, mp 259-261° C.
