[Anilides with Analgesic and Antipyretic Activity]

Several trimethylcyclopentyl and trimethylcyclopentenyl acetanilides, mono- and di-substituted on the aromatic nucleus as well as the corresponding acyl derivatives from aniline it self and corresponding phenylacetanilides, were prepared and tested as analgesics and antipyretics. Several compounds exhibit considerable activity in some cases superior to that of acetanilide.
