Novel 4-(2-oxo-1-cycloalkylidenemethyl)phenylacetic acid derivatives and non-toxic pharmaceutically acceptable salts thereof are useful as anti-inflammatory agents. The compounds may be prepared by reacting a p-formylphenylacetic acid ester derivative with an enamine of cycloalkanone and hydrolyzing the resulting product, or with a cycloalkanone in the presence of a base.
