FIELD: chemistry.
SUBSTANCE: invention relates to organic chemistry and chemical engineering, specifically to production of 7-[N'-(4-trifluoromethylbenzoyl)-hydrazinocarbonyl]-tricyclo[3.2.2.02,4]non-8-ene-6-carboxylic acid (1) as shown in the diagram below. Disclosed is a method in which compound (1) is obtained by reacting endo-3,3a,4,4a,5,5a,6,6a-octahydro-1,3-dioxo-4,6-ethenocycloprop[f]-furan and 4-trifluoromethylbenzoic acid hydrazide in dimethyl sulphoxide at 20-30 °C for 1-3 hours, followed by precipitation of the product with water, filtration, washing and drying.
EFFECT: high efficiency of synthesis, simple filtering step and high safety of the process; disclosed method is suitable for producing a drug for orthopox viruses.
