Procedure
A modification of the general method described in Example 41 was followed using 1-(2-methylpropyl)-7-(2-nitrophenoxy)-2-propyl-1H-imidazo[4,5-c]quinolin-4-amine, prepared as described in Example 36, in lieu of 1-(2-methylpropyl)-7-(4-nitrophenoxy)-2-propyl-1H-imidazo[4,5-c]quinolin-4-amine. When the reaction was complete, the reaction mixture was filtered through a layer of CELITE filter aid, and the filter cake was washed with methanol and methanol:dichloromethane. Following treatment with the ion exchange resin, the crude product was purified by column chromatography on silica gel (eluting with dichloromethane:methanol ranging in ratios from 98:2 to 94:6). The white, waxy solid was recrystallized from acetonitrile to yield 0.150 g of 7-(2-aminophenoxy)-1-(2-methylpropyl)-2-propyl-1H-imidazo[4,5-c]quinolin-4-amine as tan crystals, mp 197-199° C.
