Acetylacetone → HCID 20302971, compound

Participants

Reaction Steps

21.2 g (0.1 mol) of 7-chloro-3-hydrazino-benzo-1,2,4-triazine 1-oxide were boiled under reflux with 10 g (0.1 mol) of acetylacetone in 200 ml of ethanol for 5 hours. After cooling, the reaction product which had precipitated was filtered off, washed with ethanol and dried. 20.2 g of 3-(3,5-dimethyl-pyrazol-1-yl)-7-chlorobenzo-1,2,4-triazine 1-oxide of melting point 198°-200° C. (from dimethylformamide) were obtained, that is to say 73% of theory.
