Reaction Conditions

Reaction Steps

A mixture of 67.5 g (0.213 mole) of 1-(2-benzoyloxyethyl)-1H-imidazo[4,5-c]quinoline (from Example 115), 36.3 g (0.32 mole) of 30% hydrogen peroxide and 450 ml of glacial acetic acid was heated at 65° C. for 2 days with stirring. The solution was evaporated in vacuo, and the residue was then added to water. The mixture was neutralized with aqueous sodium hydroxide solution and sodium bicarbonate. The solid was separated by filtration, washed with water and recrystallized form methanol to provide tan solid 1-(2-benzoyloxyethyl)-1H-imidazo[4,5-c]-quinolin-5-oxide.
