Versuchsvorschrift

A mixture of aniline (18.6 parts), 2-ethylhexyl bromide (42.4 parts), anhydrous potassium carbonate (30.3 parts) and dry N,N-dimethylformamide (100 parts) was stirred at 75° C. for 24 hours. The cooled mixture was filtered, diluted with dichloromethane and washed with 2N-hydrochloric acid (100 parts). The organic phase was evaported to leave oil which was triturated with petroleum ether and water to give N-(2-ethylhexyl)aniline (18 parts, 43%).
