Vorschrift

15 g of a 70% aqueous ethylamine solution is added to 28.9 g of 2,4-dichloro-6-(2,2,6,6-tetramethylpiperidin-1-yl)-1,3,5-triazine (prepared according to Example 1) in 250 ml of ethanol at room temperature. The temperature climbs rapidly to about 35°. The mixture is subsequently stirred at 55° for 12 hours, 25 ml of water are added and the mixture is cooled to 5°. The resulting precipitate is filtered off, washed with 200 ml of water and dried. 2-Chloro-4-ethylamino-6-(2,2,6,6-tetramethylpiperidin-1-yl)-1,3,5-triazine is obtained by crystallization from acetonitrile as colorless crystals having a melting point of 148°.
