Versuchsvorschrift

6-Chloro-8-methyl-[1,2,4]triazolo[4,3-b]pyridazin-3-ylamine hydrobromide (W2.002; 2.5 g) were dissolved in ethanol (50 ml), admixed under argon with sodium ethoxide (3.86 g) and stirred at 60° C. for 1 h. Then the mixture was dried and the residue was purified using a 40 g silica gel cartridge (0-20% dichloromethane-ethanol gradient in 40 min). The clean product fractions were combined and dried. 1.76 g of the title compound were obtained.
