Participants

Reaction Steps

To a solution of 4-[5-(4-trifluoromethylbenzoylamino)pyridin-2-yloxy]benzoic acid (4.30 g, 10.7 mmol) in DMF (150 mL) were added 1-(2-oxo-1,2,3,4-tetrahydroquinoline-6-ylmethyl)-piperazine (2.6 g, 10.7 mmol), 1-hydroxybenzotriazole monohydrate (1.64 g, 10.7 mmol) and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (2.46 g, 12.8 mmol) under ice cooling, and the resulting solution was stirred for 1 hour under ice cooling and for 17 hours at room temperature. This reaction solution was concentrated under reduced pressure. To the residue was added a saturated sodium bicarbonate solution, and extracted with ethyl acetate. The ethyl acetate layer was washed with a saturated sodium bicarbonate solution and brine, dried over anhydrous magnesium sulfate, and evaporated. The residue was recrystallized from ethyl acetate, to thereby yield 5.24 g of the title compound.
