Abstract

On prépare le tricyclazole par réaction du 2-hydrazino-4-méthylbenzothiazole avec un excès d'acide formique. On enlève l'excès d'acide formique par distillation azéotrope avec un hydrocarbure aromatique et on isole le produit par cristallisation dans l'hydrocarbure. Préparation améliorée du tricyclazole, qui est un composé permettant de lutter contre les organismes phytopathogenes.
