実験手順
Benzyl chloride (250 g.) was added dropwise to a solution of 3,4-diethylpyridine (262 g., Beilsteins Handbuch der Organischen Chemie, Vierte Auflage, Julius Springer, Berlin, 1935 p. 253) in isopropyl alcohol (700 ml.). The resulting solution was refluxed (for 2 hr.), then concentrated under water pump vacuum. Benzene (250 ml.) was added to the residue and the solution was concentrated again. The process was repeated with two further portions (250 ml. and 500 ml.) of benzene. The residue began to crystallize. Benzene (2250 ml.) was added, affording a thick slurry of 1-benzyl-3,4-diethylpyridinium chloride.
