FIELD: pharmacological products.
SUBSTANCE: invention is related to a method for producing 3-aroylbenzo[d]pyrrolo[2,1-b]thiazol-1,2-diones, which can be used as starting products for the synthesis of new heterocyclic systems and in pharmacology. The method involves the interaction of 3-aroylpyrrolo[2,1-c][1,4]benzothiazine-1,2,4-triones with diphenylcarbinol in an aprotic solvent (toluene) when heated at 113°C for 2 hours:
I, III: Ar = C6H5 (a); Ar = C6H4Me-4 (b); Ar = C6H4Cl-4 (c).
EFFECT: development of a simple method for synthesis of 3-aroylbenzo[d]pyrrolo[2,1-b]thiazole-1,2-diones.
