실험 절차
Triethylamine (1.04 mL, 7.46 mmol) was added to a 0° C. solution of 1-allyl-4-chloro-2-(ethoxymethyl)-1H-imidazo[4,5-c]quinoline (1.50 g, 4.97 mmol) and N-hydroxyethanimidoyl chloride (581 mg, 6.21 mmol) in dichloromethane (80 mL). The reaction solution was allowed to warm slowly to room temperature and stir overnight under a nitrogen atmosphere. After 20 hours, the solution was washed with saturated aqueous sodium bicarbonate and brine, dried over magnesium sulfate, filtered, and concentrated. The crude product was purified by flash chromatography (silica gel, elution with 98:2 dichloromethane/methanol) to yield 4-chloro-2-(ethoxymethyl)-1-[(3-methyl-4,5-dihydroisoxazol-5-yl)methyl]-1H-imidazo[4,5-c]quinoline (1.34 g) as a white solid.
