Showed that this compounds were condensed easily with 3-amino-5-R-1,2,4-triazoles in acetic acid. The products of this reaction are condensed heterocycles, containing pyrimidine ring.The claim for preparative means receipt of 3-аmino-2-thioxо-1,2,3,4-tetrahydroquinazolin-4-one moved. Established that the antranilic acid hydrazide is the starting material for synthesis of 5-(2-aminophenyl)-2,3-dihydro-1,3,4-oxadiazolo-2-thion.
