Versuchsvorschrift

A mixture of 3,4-lutidine (112 mL, 1.0 mole), benzyl chloride (115 mL, 1.0 mole) and isopropanol (500 mL) was refluxed under nitrogen for 5 hours and then was stirred at room temperature for 60 hours. The mixture was diluted with ether and the resulting white precipitate was filtered and dried to afford 178.3 g (76%) of N-(phenylmethyl)-3,4-dimethylpyridinium chloride.
