Reaction Steps
6-Chloro-7-methyl-[1,2,4]triazolo[4,3-b]pyridazin-3-ylamine (W2.005; 1 g) was dissolved in ethanol (50 ml), admixed under argon with sodium ethoxide (2.2 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. 480 mg of the title compound were obtained.
