| titleOfInvention | Method of producing 4-(3-nitro-4-aminophenyl)-1(2n)phthalazinone |
| abstract | The invention relates to heterocyclic compounds, in particular to the 1k ray of 4- (3-nitro-4-aminophenyl-1 (210 phthalazinone (NAF)), which, as an intermediate product for the synthesis of the anthelminthic drug phthalbendazole. With the aim of simplifying the technology and increasing the yield of PAF 3-yitro-4-chlorobenzo ({) enon-2-car-. The acid is reacted with gaseous ammonia in ethylene glycol medium. The resulting reaction mass is treated with hydrazineudate at 70-80 ° C. 85%. The method allows to obtain NAF in one stage. |
