| titleOfInvention | Method of producing mononitrobenzocrown esters |
| abstract | The invention relates to heterocyclic substances, in particular the preparation of 3-benzoylmethylene or 3- (N-methylbenzoylmethylene) -2-piperazinones, which possess valuable biological properties. The goal is to increase the yield of the target product and simplify the process. The latter is carried out by the reaction of methyl esters of benzoyl or methyl benzoyl pyruvic acid with ethylene diamine in the presence of acetic acid at a ratio of 1: 1: 10 in toluene at reflux. These conditions allow the synthesis time to be reduced to 1 hour while simplifying the procedures for the isolation of target substances, which are formed with a yield of 98% versus 81-86% in the known case. |
