Ammonia → 2-(ethoxymethyl)-1-[(3-methylisoxazol-5-yl)methyl]-1H-imidazo[4,5-c]quinolin-4-amine

Participants

Reaction Steps

A slurry of 4-chloro-2-(ethoxymethyl)-1-[(3-methylisoxazol-5-yl)methyl]-1H-imidazo[4,5-c]quinoline (4.21 g, 11.8 mmol) in a solution of 7 M ammonia in methanol (50 mL) was heated at 150° C. for 22 hours in a Parr pressure vessel. The volatiles were removed under reduced pressure and the resulting solid was triturated with water. A tan solid was isolated and purified by flash chromatography (silica gel, gradient elution from 9:1 to 1:1 chloroform/CMA) to yield 43.2 mg of pure 2-(ethoxymethyl)-1-[(3-methylisoxazol-5-yl)methyl]-1H-imidazo[4,5-c]quinolin-4-amine as a white powder, mp 178.0-180.0° C.
