Reaction Steps

2-(2,4-Dichlorophenoxy)acetic acid (310 mg) was added to chloroform (5 ml), and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (403 mg), 1-hydroxybenzotriazole monohydrate (284 mg), and 4-[(6,7-dimethoxy-4-quinolyl)oxy]aniline (498 mg) were added thereto. The mixture was then stirred with heating under reflux for 2 hr. A saturated aqueous sodium hydrogencarbonate solution was added to stop the reaction, and the reaction solution was extracted with chloroform, followed by washing with a saturated aqueous sodium hydrogencarbonate solution, 1 N hydrochloric acid, water, and saturated brine. The extract was then dried over sodium sulfate. After the concentration of the extract, the residue was purified on a column using chloroform/methanol to give N1-{4-[(6,7-dimethoxy-4-quinolyl)oxy]phenyl}-2-(2,4-dichlorophenoxy)acetamide (500 mg, yield 72%).
