Reaction Steps

To a stirred suspension of 1.0 g (0.0054 mole) of 1H-imidazo[4,5-c]quinolin-4-amine in 10 mL of N,N-dimethylformamide was added 0.15 g (0.0059 mole) of sodium hydride. To this stirred mixture was added 0.74 g (0.0054 mole) of isobutyl bromide. After 30 minutes the mixture was heated at about 100° C. for one hour. The mixture was cooled to about 20° C., diluted with 20 mL of water, and the solid was separated by filtration. Recrystallization from N,N-dimethylformamide provided the known antiviral agent 1-(2-methylpropyl)-1H-imidazo[4,5-c]quinolin-4-amine.
