%X A yellow product formed in the reaction of 2,4-di-p-methylanilinocyclopent-2-enone with maleic anhydride has been shown by X-ray crystallographic analysis to be (4&#8242;-p-methylanilino-1&#8242;-p-methylphenyl-2&#8242;,5&#8242;-dioxo-1&#8242;,2&#8242;,3&#8242;,5&#8242;,6&#8242;,6&#8242;a- hexahydrocyclopenta[b]pyrrol-3&#8242;-yl)acetic acid (3) in accord with the spectroscopic data. Monoclinic crystals of (3) belong to the space group P21/n with a 13.399(2), b 8.386(1), c 17.935(3)&#506;, &#946; 92.06(2)&#176; and Z 4. Full-matrix refinement with 2292 observed data converged at R 0.063.
