  • Process for the preparation of 2-chloro-5-methylpyridine-3-carbaldehyde
    Patent number: 6479664
    Abstract: The present invention describes an improved process for the preparation of 2-chloro-5-methylpyridine-3-carbaldehyde from N-benzyl-N-(1-Propenyl)acetamide using diphosgene and dimethylformamide or triphosgene and dimethylformamide (Vilsmeyer reagent) in 92% yield against reported 12% yield. The present invention has the advantage of using diphosgene and triphosgene instead of toxic phosgene gas and phosphorousoxytrichloride, thereby avoiding the formation of phosphorous salt.
