Reaktionsschritte

A mixture of 1,5-bis(4-methoxyphenyl)-1H-1,2,4-triazol-3-ol (0.3 g, 1.01 mmol), potassium carbonate (418 mg, 3.01 mmol), and iodoethane (0.406 mL, 5.05 mmol) in dimethylformamide (3 mL) was stirred for 3 days. Water and ethyl acetate-tetrahydrofuran (9:1) were poured into the mixture and the organic layer was separated, washed with brine-water (1:1) and brine, and dried over magnesium sulfate. The solvent was removed under reduced pressure. The residue was purified by column chromatography to give 3-ethoxy-1,5-bis(4-methoxyphenyl)-1H-1,2,4-triazole (143 mg, 43.6% yield).
