METHOD OF PREPARING SUBSTITUTED 2-(PHENYLAMINO)-2- IMIDAZOLINES

摘要

FIELD: chemical industry. SUBSTANCE: substituted 2-(phenylamino)-2-imidazolines of formula I: wherein R¹= R²= Cl and R³= H, CH₃, F, are prepared by condensation of anilines with 1-benzoylimidazolidin-2-one in phosphorus oxychloride in the presence of lithium halides or quaternary ammonium bases. Presence of lithium salts reduces reaction time up to 20-24 hours. EFFECT: high quality of the desired compounds. 6 ex
