The reaction between chloromaleic acid anhydride and phenylhydrazine is studied. The constitution of the two isomeric 1-phenyl-3-hydroxy-chloro-pyridazones-(6) is established. Starting with 1-phenyl-3-hydroxy-4-chloro-pyridazone-(6) some derivatives are prepared. Some of them show good analgesic activity.
