HCID 1358174912-[3,5-Bis(2-hydroxyphenyl)-[1,2,4]triazol-1-yl]-N-(2-methoxyethyl)acetamide

Procedure

4.0 g of ethyl [3,5-bis(2-hydroxyphenyl)-[1,2,4]triazol-1-yl]acetate (Example 2) are dissolved in 30 ml of 2-methoxyethylamine and the mixture is stirred at room temperature for 2 h. It 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-methoxyethyl)acetamide remains as colorless crystals of m.p. 184-186° C.
