Reaction Steps
3.0 g of 6-chloro-2-(5-chloro-2-hydroxyphenyl)benz[e][1,3]oxazin-4-one and 1.7 g of 4-hydrazinobenzoic acid are boiled under reflux for 2 h in 40 ml of ethanol. The crystals precipitating on cooling are recrystallized from isopropanol. After drying, 4-[3,5-bis(5-chloro-2-hydroxyphenyl-[1,2,4]triazol-1-yl]benzoic acid remains as colorless crystals of m.p. 275-278 C.
