The reaction of phenylhydrazine with maleic acid anhydride and with citraconic acid anhydride was studied. The cyclic phenylhydrazides (1-phenyl-3-hydroxy-6-pyridazones) obtained in this way served as starting materials for the preparation of substituted 1-phenyl-6-pyridazones. Some of them show analgesic and antipyretic activity.
