Versuchsvorschrift

Dioctadecylamine (26.0 g., 0.05 M), α-bromo-p-tolunitrile (4.9 g., 0.025 M) and chloroform (500 ml.) are stirred at room temperature for 24 hours. The precipitate of dioctadecylamine hydrobromide is filtered off and the filtrate concentrated under reduced pressure. The residue is slurried in methanol, filtered, and evaporated to give 1-(dioctadecylamino)methyl-4-cyanobenzene (15.5 g., 97.5% yield).
