실험 절차

2.0 g of ethyl [3,5-bis(2-hydroxyphenyl)-[1,2,4]triazol-1-yl]acetate (Example 2) and 1.0 g of N,N-bis(2-hydroxyethyl)ethylenediamine are boiled under reflux for 24 h in 8 ml of ethanol. The mixture is cooled, poured onto water and extracted with ethyl acetate. The combined organic phases are dried over sodium sulfate and concentrated on a rotary evaporator. The residue is chromatographed on silica gel. After concentration and drying, N-{2-[bis(2-hydroxyethyl)amino]ethyl}-2-[3,5-bis(2-hydroxyphenyl)-[1,2,4]triazol-1-yl]acetamide remains as a colorless foam. Rf value: 0.35 (silica gel 60, methylene chloride/methanol=9/1). 1H-NMR (DMSO-d6): 2.5 (m, 6H), 3.1 (m, 2H), 3.4 (m, 4H), 4.2 (bs, 2H), 4.9 (s, 2H), 7.0 (m, 4H), 7.4 (m, 3H), 7.95 (d, 1H), 8.1 (t,1H), 11.0 ppm (s, 1H).
