| description | The present invention relates to a method for preparing a bisamide insecticide or an intermediate thereof. Specifically, the present invention relates to a method for preparing a compound of formula I. The method comprises the step of reacting a carboxylic acid as represented by formula I-1 with a halogenating agent and elemental halogen. The method can substantially improve product yield, producing relatively high economic benefits.
La présente invention concerne un procédé de préparation d'un insecticide bisamide ou d'un intermédiaire de celui-ci. Spécifiquement, la présente invention concerne un procédé de préparation d'un composé de formule I. Le procédé comprend l'étape de réaction d'un acide carboxylique tel que représenté par la formule I-1 avec un agent d'halogénation et un halogène élémentaire. Le procédé peut sensiblement améliorer le rendement du produit, produisant des avantages économiques relativement élevés.
