実験手順

To a solution of ({4-[5-(3,4-dichlorobenzoyl-amino)pyridin-2-yloxy]phenyl}methylamino)acetic acid (2.50 g, 5.6 mmol) in DMF (55 mL) were added 1-(2,3-dihydrobenzo[1,4]dioxin-6-ylmethyl)piperazine (1.7 g, 7.3 mmol), 1-hydroxybenzotriazole monohydrate (0.86 g, 5.6 mmol) and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (1.29 g, 6.7 mmol) under ice cooling, and the resulting solution was stirred for 30 minutes under ice cooling and for 17 hours at room temperature. This reaction solution was concentrated under reduced pressure. Water was added to the residue, 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 dissolved in ethanol (30 mL). To the resulting solution was added maleic acid (0.32 g, 2.7 mmol), and this solution was left to stand. The precipitates were collected by filtration, to thereby yield 1.45 g of the title compound.
