| Product | Ethyl 3-(6-phenyl-3-pyridazinyl)carbazate | HCID 20326484 | — |
Reaction Steps
A mixture of 15.0 g. of 6-phenyl-3-chloropyridazine, 16.3 g. of ethyl carbazate, and 250 ml. of n-butanol is refluxed for 3 hours. The solvent is removed under vacuum and the residue triturated with cold water. Filtration gives 18.6 g. of cream colored crystals. Recrystallization gives white crystals, m.p. 158°-160° C.
