Participants

Reaction Steps

19.5 g (0.1 mol) of 3-hydrazino-7-chloro-benzo-1,2,4-triazine and 10 g (0.1 mol) of acetylacetone were boiled under reflux in 125 ml of ethanol for 5 hours. The residue after distilling off the solvent was recrystallized from wash benzine. 22.3 g of 3-(3,5-dimethyl-pyrazol-1-yl)-7-chloro-benzo-1,2,4-triazine of melting point 174° C. were obtained, that is to say 86% of theory.
