Reaction Steps

2-Azidomethyl-1(2-methylpropyl)-1H-imidazo[4,5-c]quinolin-4-amine (3.2 g, 0.0108 mol, Example 11) was added to ethanol (300 mL) and 5% Pd/C (about 1 g) was added to the mixture. The mixture was hydrogenated on a Parr apparatus until hydrogen uptake stopped. Hydrogen was removed and the mixture was flushed with hydrogen to regenerate the catalyst. Hydrogenation was resumed. This procedure was repeated until no more hydrogen was absorbed. The catalyst was filtered from the mixture and the filtrate was evaporated. The residue was recrystallized several times from ethanol to give yellowish crystals m.p. 287°-291° C. Analysis: Calculated: C, 66.9; H, 7.1; N, 26.0. Found: C, 66.5; H, 7.2; N, 25.1.
