The existance of the tautomeric equilibrium of imidazolidine system 34has been established.Due to a higher reactivity of NH group in 4, the reaction of the system 34 with PhNCO unbalances the tautomeric equilibrium, and causes an increase in the content of the open-chain urea derivative 6 in the reaction mixture.The use of isocyanates or other similar reagents, e.g., isothiocyanates, seems to be a convenient method for studies of the tautomerism in similar system.
