FIELD: organic chemistry.
SUBSTANCE: invention relates to new method for production of E-2-aroylmethylene-1-phenyl-1,2,3,4-tetrahydroquinazolin-4-ones of general formula I 
wherein R represents H, methyl, Cl. Claimed method includes interaction of 5-aryl-2,3-dihydro-2,3-furandiones with N-phenylanthranyl acid amide in medium of inert aprotic solvent (preferably benzene) followed by isolation of target products. Process is carried out preferably at 79-80°C. Claimed compounds have fluorescent properties and are useful in labeling and copying agents, intermediates for synthesis of new heterocyclic compounds, etc.
EFFECT: new fluorescent compounds.
