Procedure

The general method described in Parts I and J of Example 28 was used to aminate 6-methyl-1-(2-propyl-1H-imidazo[4,5-c]quinolin-1-yl)heptan-4-one (2.40 g, 7.10 mmol) by reaction with m-CPBA (3.9 g) to provide 6-methyl-1-(5-oxido-2-propyl-1H-imidazo[4,5-c]quinolin-1-yl)heptan-4-one followed by reaction with p-toluenesulfonyl chloride (2.0 g, 10.5 mmol) and ammonium hydroxide solution (75 mL) to provide 1-(4-amino-2-propyl-1H-imidazo[4,5-c]quinolin-1-yl)-6-methylheptan-4-one as tan crystals after recrystallization from aqueous methanol, mp 136-138° C.
