Reaction Steps

2-{4-[(6,7-Dimethoxy-4-quinolyl)oxy]phenoxy}acetic acid (150 mg), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (WSC.HCl) (122 mg), and 1-hydroxybenzotriazole hydrate (HOBT.H2O) (86 mg) were dissolved in chloroform (5 ml) to prepare a solution. o-Anisidine (63 mg) was then added to the solution, and the mixture was heated under reflux for 3 hr. A saturated aqueous sodium hydrogencarbonate solution was added to the reaction solution, and the mixture was extracted with chloroform. The chloroform layer was washed with 1 N hydrochloric acid, water, and saturated brine and was then dried over anhydrous sodium sulfate. The solvent was removed by distillation under the reduced pressure. The residue was purified by thin-layer chromatography using chloroform/methanol for development to give the title compound (155 mg, yield 80%).
