FIELD: heterocyclic compounds. SUBSTANCE: product: 1-amino-8,9-dihydro-5,8,8-trimethyl-3,6H-pyrazolo(3,4-b)thiop- yrano(4,3-d)pyridine or its hydrochloride. Synthesis is carried out from 2,2-dimethyl-4-(N-morpholino)-2,3-dihydro-6H-thiopyrane and acetic acid chloroanhydride by cyclization of synthesized product with cyanacetamide, conversion of the latter product to the corresponding chloro-derivative and its cyclization with hydrazine hydrate followed by conversion to hydrochloride. Synthesized compounds show anticonvulsant action. EFFECT: improved method of synthesis. 1 tbl
