Abstract
The present invention pertains to a process for producing a 2-imidazolone from a ureidoacetal. The ureidoacetal is subjected to an acid catalyzed condensation in order to produce the 2-imidazolone. The reaction is conducted in an alcoholic solvent in order to minimize the production of a polymeric by-product.
