FIELD: chemistry.
SUBSTANCE: invention refers to organic substances production and can be applied for production of herbicides and other bioactive compounds. Production of 2-sulphanilamine-1,2,4-triazolo[1,5-a]pyrimidine of general formula 
, where R1 is metal, phenylic, 4-methyl phenylic, 4-chlorophenylic group, R is phenylic, 4-methyl phenylic, 4-chlorophenylic, methoxyphenylic group, R is metal, phenylic, 4-methyl phenylic, 4-chlorophenylic group is sulphurization of 2-amino-4,7-dihydro-1,2,4-triazolo [1,5-a]pyrimidines (II) by sulphochlorides (III) in pyrimidine and oxidation of produced 2-sulphanilamine-4,7-dihydro-1,2,4-triazolo[1,5-a] pyrimidines (IV) by bromine in acetic acid with sodium acetate occurrence.
EFFECT: method allows to produce compounds using low-price and reasonable raw materials without any complicated processing steps applied.
