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 1H and 13C{1H} 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.
