Abstract

FIELD: heterocyclic compounds. SUBSTANCE: desired compound is prepared by catalytic reduction of 3-(3″-nitrobenzoylamino)-1-(2′,4′,6′-trichlorophenyl)-pyrazolone-5 with the help of 98-100 % hydrazine hydrate or hydrogen. The process is carried out at atmospheric pressure in 0.5-5. % aqueous-alkali solution, it is followed by treatment thus prepared reaction mass with acid (e.g sulfuric acid, hydrogen chloride acid or acetic acid). Yield of desired product is 95-97 %. EFFECT: simplified process, decreased explosion and fire hazard. 2 cl
