Vorschrift

A mixture of freshly distilled aniline (93 g, 1 mol), potassium carbonate (210 g, 1.5 mol), octadecyl bromide (840 g, 2.5 mol), sodium iodide (7.5 g, 0.05 mol), and 1 liter of butanol was heated at reflux for 72 hours under nitrogen with vigorous stirring. The hot solution was filtered and the filtrate was evaporated under reduced pressure. The residue was recrystallized from absolute ethanol to yield 322 g (54%) of off-white crystals mp 110°-111° C.
