2-Ethoxymethyl-1-(3-isopropoxypropyl)-7-(morpholin-4-yl)-1H-imidazo[4,5-c]quinoline (1.0 g), benzonitrile (0.44 mL) and sodium bicarbonate (0.15 g) were slurried in methanol. Hydrogen peroxide (55% by weight in water, 0.395 mL) was added dropwise over 1 hour. The reaction was stirred overnight. The methanol was removed under reduced pressure and the residue was purified by column chromatography on a Biotage Horizon™ High Performance Flash Chromatography instrument. The purification was carried out eluting with chloroform:CMA in a gradient from 98:2 to 75:25. 2-Ethoxymethyl-1-(3-isopropoxypropyl)-7-(morpholin-4-yl)-1H-imidazo[4,5-c]quinoline 5-oxide was isolated as a yellow oil (0.166 g).
