FIELD: chemistry.
SUBSTANCE:
which involves recyclisation of a furan ring of 2-amino-N-(furan-2-ymethyl)acetamides at room temperature in a mixture of glacial acetic acid and concentrated hydrochloric acid for 24 hours, after which sodium bicarbonate is added and then boiled for 5 minutes.
EFFECT: novel method of producing 1,2-dihydropyrrolo[1,2-α]pyrazin-3(4H)-ones as a result of simultaneous formation of a pyrrole ring and a pyrazine ring, which in turn can be used as biologically active substances.
