Procedure

2.0 g of ethyl [3,5-bis(2-hydroxyphenyl)-[1,2,4]triazol-1-yl]acetate (Example 2) are dissolved in 10 ml of ethanolamine and stirred at room temperature for 2 h. The mixture is concentrated to dryness in vacuo and the residue is crystallized from isopropanol. After drying, 2-[3,5-bis(2-hydroxyphenyl)-[1,2,4]triazol-1-yl]-N-(2-hydroxyethyl)acetamide remains as colorless crystals of m.p. 208-211° C.
