실험 절차

A mixture of 4-[2-(3-ethyl-4H-triazol-4-yl)ethoxy]aniline (1.12 g), 3-(5-phenyl-4-isoxazolyl)propionic acid (1.04 g), 1-hydroxy-1H-1,2,3-benzotriazole hydrate (0.89 g), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (1.11 g) and N,N-dimethylformamide (20 ml) was stirred at room temperature overnight. The reaction mixture was poured into water and the mixture was extracted with ethyl acetate. The ethyl acetate layer was washed with dilute hydrochloric acid, saturated aqueous sodium hydrogencarbonate and then saturated brine, dried (MgSO4) and concentrated. The residue was subjected to silica gel column chromatography, and N-[4-[2-(3-ethyl-4H-triazol-4-yl)ethoxy]phenyl]-3-(5-phenyl-4-isoxazolyl)propionamide (1.58 g, yield 76%) was obtained as colorless crystals from a fraction eluted with ethyl acetate-hexane (1:1, volume ratio). The crystals were recrystallized from acetone-hexane. melting point: 167–168° C.
