3-Amino-1,2-propanediol → 2-[3,5-Bis(2-hydroxyphenyl)-[1,2,4]triazol-1-yl]-N-(2,3-dihydroxypropyl)-acetamide

Participants

Reaction Steps

2.0 g of ethyl [3,5-bis(2-hydroxyphenyl)-[1,2,4]triazol-1-yl]acetate (Example 2) and 2.4 g of (+/−)3-amino-1,2-propanediol are heated at 60° C for 2 h in 10 ml of ethanol. The crystals precipitating on cooling are filtered off and washed with ethanol. After drying, 2-[3,5-bis(2-hydroxyphenyl)-[1,2,4]triazol-1-yl]-N-(2,3-dihydroxypropyl)acetamide remains as colorless crystals of m.p. 180-181° C.
