Procedure

The general method described in Steps 9 and 10 of Example 1 was used to aminate ethyl 3-(2-propyl-1H-imidazo[4,5-c]quinolin-1-yl)propionate (3.30 g, 10.6 mmol) by reaction with m-CPBA (4.63 g) to provide ethyl 3-(5-oxido-2-propyl-1H-imidazo[4,5-c]quinolin-1-yl)propionate followed by reaction with p-toluenesulfonyl chloride (3.53 g, 18.6 mmol) and ammonium hydroxide solution (50 mL) to provide ethyl 3-(4-amino-2-propyl-1H-imidazo[4,5-c]quinolin-1-yl)propionate as an off-white solid after recrystallization from aqueous methanol, mp 156-157° C.
