실험 절차

Potassium carbonate (279 mg, 2.02 mmol) and potassium iodide (335 mg, 2.02 mmol) was added to a solution of 1,5-bis(4-methoxyphenyl)-1H-1,2,4-triazol-3-ol (200 mg, 0.673 mmol) in dimethylformamide (2 mL). After 5 minutes stirring, 3-(chloromethyl)-1,2,4-oxadiazole (239 mg, 2.02 mmol) was added to the mixture and the mixture was heated at 100° C. for 1 hour. After cooling, ethyl acetate and water were poured into the mixture. The organic layer was separated, washed with water and brine, and dried over magnesium sulfate. The solvent was removed under reduced pressure. The residue was purified by preparative-TLC (toluene-ethyl acetate 4:1). The desired product was triturated with isopropylether, isolated by filtration, and dried in vacuo to give 3-({[1,5-bis(4-methoxyphenyl)-1H-1,2,4-triazol-3-yl]oxy}methyl)-1,2,4-oxadiazole (110 mg, 43.1% yield).
