FIELD: chemistry.
SUBSTANCE: invention relates to methods of obtaining new functionally substituted fused heterocyclic molecules -1-imino-2,3,4,5-tetrahydro-1H-pyrrolo[3,4-c]pyridine-3,4-diones of the formula (I) 
wherein R1=R2=Me (1a); R1=Me, R2=Et (1b); R1+R2=(CH2)4 (1c); R1+R2=(CH2)5 (1d); R1+R2=(CH2)6 (1e), which may be employed as biologically active compounds in organic synthesis and as fluorescent dyes. The production method consists in suspending the corresponding 2-oxo-4-cyano-1,2-dihydropyridine-3-carboxamide in ethanol, followed by the addition of aqueous ammonia solution with the concentration of 20%, after which the reaction mass is boiled for 30 minutes to obtain the desired product.
EFFECT: new compounds with useful biological activity are obtained.
