Versuchsvorschrift

To 67.5 parts of the quaternary salt of 2-picoline, also called 2-methylpyridine, (obtained as in Example 13) was added 100 parts methanol, one part piperidine, and 37 parts benzaldehyde. The solution was boiled at reflux for three hours, 175 parts 40% sodium hydroxide solution was added, and the heating continued 1.5 hour to give on workup, as in Example 13, 27 parts 2-styrylpyridine.
