Versuchsvorschrift

In 100 ml of benzene is dissolved 14 g of 2-methyl-3-chloroaniline obtained in Reference Example 1 and, after adding 12 g of triethylamine, 13 g of ethyl bromide is added to the solution to conduct the reaction under reflux of benzene for 3 hours. After the completion of the reaction, the mixture is cooled to room temperature and shaken with 200 ml of water. The benzene layer is separated, dried over anhydrous magnesium sulfate, and concentrated. Distillation of the residue results in 12 g of N-ethyl-2-methyl-chloroaniline as the fraction of 125°-126° C./10 mmHg.
