Bald, Edward published the artcileThe synthetic utility of 2-halopyridinium salts. Preparation of pyridinemonocarboxylic esters and amides under mild conditions, Related Products of amides-buliding-blocks, the publication is Chemica Scripta (1979), 13(1), 47, database is CAplus.
The equimolar reaction of pyridinemonocarboxylic acids with alcs. or amines and 2-chloro-1-methylpyridinium iodide in the presence of 2 M amounts of Et3N gave the corresponding pyridinemonocarboxylic esters or amides in good yields.
