Abstract

Procédé de préparation de 2-cyano-4,5-diméthyl-pyridine. On fait réagir le N-oxyde de 3,4-lutidine sur le sulfate de diméthyle pour obtenir le méthylsulfate de 1-méthoxy-3,4 diméthylpyridinium, puis on traite celui-ci sous atmosphère inerte pendant 24 heures entre 0 degrés et 5 degrés C par une solution de cyanure alcalin pour obtenir le composé :
