Procedure

To 140 parts 4-picoline, also commonly called 4-methylpyridine, was added 540 parts of a 21.5% solution of hydrogen chloride in isopropanol, then 236 parts 2-vinylpyridine was added, and the resultant solution heated to 90° C. for 16 hours. The mixture was cooled to 30° C. and filtered to give 300 parts 1-[2-(2-pyridyl)ethyl]-4-picolinium chloride hydrochloride.
