• 1) 4-Benzamido-6-chloro-3-pyridazinol (IV) was obtained from 4-amino-6-chloro-3-pyridazinol (III) by heating with benzoyl chloride under reflux in the presence of pyridine or nitrobenzene as a solvent. 2) 2-Phenyl-6-chlorooxazolo[5,4-c]pyridazine (I) yielded (III) and (IV) on heating with sodium hydroxide solution and hydrochloric acid, respectively.
