A process for preparing 2-(2-furoyl)-1,4-dimethylpyridinium iodide comprising the steps of reacting 2-cyano-4-methylpyridine under a nitrogen atmosphere with an ethereal solution of freshly prepared 2-furyl-lithium, hydrolyzing the reaction mixture under acid conditions to form 2-(2-furoyl)-4-methylpyridine, and heating the 2-(2-furoyl)-4--methylpyridine in the presence of methyl iodide to form 2-(2-furoyl)-1,4-dimethylpyridinium iodide.
