65 °C

A mixture of 67.5 g (0.213 mole) of 1-(2-benzoyloxyethyl)-1H-imidazo[4,5-c]quinoline (from Example 118), 36.3 g (0.32 mole) of 30% hydrogen peroxide and 450 ml of glacial acetic acid was heated at 65° C. for two days with stirring. The solution was then evaporated in vacuo, and the residue was 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 from methanol to provide tan solid 1-(2-benzoyloxyethyl)-1H-imidazo[4,5-c]-quinolin-5-oxide.
