Versuchsvorschrift
The general method described in Steps 9 and 10 of Example 1 was used to aminate 6-(1H-imidazo[4,5-c]quinolin-1-yl)-1-phenylhexan-1-one (2.0 g, 5.8 mmol) by reaction with m-CPBA (1.44 g, 6.41 mmol) to provide 6-(5-oxido-1H-imidazo[4,5-c]quinolin-1-yl)-1-phenylhexan-1-one followed by reaction with p-toluenesulfonyl chloride (1.22 g, 6.41 mmol) and ammonium hydroxide solution (10 mL) to provide 6-(4-amino-1H-imidazo[4,5-c]quinolin-1-yl)-1-phenylhexan-1-one (0.29 g) as an off-white solid after chromatography on silica gel (elution with 5% methanol in dichloromethane) and recrystallization from dichloroethane, mp 163-165° C.
