FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing ethyl 2-amino-2',5-dioxo-5'-phenyl-3-cyano-1',2'-dihydro-5H-spiro{indeno[1,2-b]pyran-4,3'-pyrrole}-4'-carboxylates of general formula 
, where R=CH2Ph, C6H11-c, H, Me, Et, carried out by reacting 5-phenyl-4-ethoxycarbonyl-1H-pyrrole-2,3-diones with malononitrile and indan-1,3-dione in the presence of triethylamine.
EFFECT: obtaining novel compounds which can be used as initial products for synthesis of novel heterocyclic systems and in pharmacology as compounds having analgesic activity.
