5-Ethoxy-1-(4-Methoxyphenyl)-5-Methyl-3-Phenylimidazolidine-2,4-Dione

The title compound is a hydantoin derivative that has been synthesized through a three-component reaction of ethyl pyruvate, p-anisidine and phenyl isocyanate. This paper provides a comprehensive spectral dataset for the title compound, including H-1 and C-13{H-1} NMR, IR, HRMS, and X-ray crystallography analyses. A tentative mechanism comprising two complementary pathways is provided based on additional experiments with the preformed intermediates.
