Studies in the cyclo-octane series: Part VI. Condensation of Cydo-octane-I-one-2-acetic Acid with  Primary Aromatic Amines and the Formation of  Substituted Pyrrol-2-ones

Ethyl 2-carbethoxy cyclooctan-1-one-2-acetate, prepared by condensing ethyl cyclooctan-1-one-2- oarboxylate with ethyl bromoacetate, on hydrolysis gave cyclooctan-1-one-2-acetic acid. This acid on refluxing with seven different primary aromatic amines furnished substituted pyrrol-2-ones.
