Procedure

The 2-butyl-1-[4-(tert-butyldimethylsilanyloxy)butyl]-1H-imidazo[4,5-c]quinoline from the previous step and tetrabutylammonium fluoride (142 mL of a I M solution in tetrahydrofuran) were dissolved in tetrahydrofuran (THF) (400 mL) and stirred for 1 hour, then concentrated under reduced pressure to provide 4-(2-butyl-1H-imidazo[4,5-c]quinolin-1-yl)butan-1-ol (20.0 g) as a light brown solid after chromatography on silica gel (elution with 10% methanol in dichloromethane).
