Participants

Reaction Steps

4-Chloro-2-(ethoxymethyl)-1-[3-(3-methylisoxazol-5-yl)propyl]-1H-imidazo[4,5-c]quinoline (1.87 g, 4.86 mmol) was treated with a solution of 7 M ammonia in methanol (20 mL) according to the procedure described in Part C of Example 5. The crude product was purified by flash chromatography (silica gel, gradient elution from 5% to 20% CMA in chloroform). The appropriate fractions were combined and concentrated to yield a solid that was triturated with 9:1 dichloromethane/methanol. The final material was dried under vacuum to yield 2-(ethoxymethyl)-1-[3-(3-methylisoxazol-5-yl)propyl]-1H-imidazo[4,5-c]quinolin-4-amine (1.29 mg) as a white powder, mp 163.0-164.0° C.
