Abstract
La présente invention est relative à un procédé pour la préparation de 3,4,5-triméthoxy-benzonitrile à partir d'acide 3,4,5-triméthoxy-benzoique. Ce procédé se caractérise en ce que l'on fait réagir l'acide 3,4,5-triméthoxy-benzoique avec de l'urée et de l'acide sulfaminique, puis on isole le 3,4,5-triméthoxy-benzonitrile ainsi obtenu. Application à la préparation des triméthoxy-benzonitrile.
