Abstract:
(EN) The present invention addresses the problem of providing a method for producing, with a high yield, a nitrogen-containing heterocyclic compound having a high purity, superior production suitability, and superior environmental suitability. The method for producing a nitrogen-containing heterocyclic compound according to the present invention comprises synthesizing a compound having a structure represented by general formula [2], by causing a reaction of a compound having a structure represented by general formula [1] with bromine in the presence of a silver salt, sulfuric acid, and a carboxylic acid.
(FR) La présente invention traite le problème de fournir un procédé de production, avec un rendement élevé, d'un composé hétérocyclique contenant de l'azote ayant une pureté élevée, une aptitude à la production supérieure, et une adéquation environnementale supérieure. Le procédé de production d'un composé hétérocyclique contenant de l'azote selon la présente invention comprend la synthèse d'un composé ayant une structure représentée par la formule générale [2], en faisant réagir un composé ayant une structure représentée par la formule générale [1] avec du brome en présence d'un sel d'argent, d'acide sulfurique et d'un acide carboxylique.
(JA) 本発明の課題は、高収率かつ高純度であり、生産適性及び環境適性に優れた含窒素複素環化合物の製造方法を提供することである。また、本発明の含窒素複素環化合物の製造方法は、下記一般式[1]で表される構造を有する化合物と臭素とを、銀塩、硫酸及びカルボン酸の存在下で反応させて、下記一般式[2]で表される構造を有する化合物を合成する。
