Procedure

6-Chloro-7,8-diisopropyl-[1,2,4]triazolo[4,3-b]pyridazin-3-ylamine (W2.015, 0.1 g) was dissolved in ethanol (15 ml) while stirring and under argon. Thereafter, the reaction mixture was admixed with sodium ethoxide (110 mg) and stirred at RT for 1 h, then at 55° C. for 1 h. Subsequently, the mixture was left to stand overnight, then stirred again at 55° C. for 7.5 h and then the solvent was drawn off, and the residue was admixed with water and extracted three times with dichloromethane. The combined organic phases were dried over sodium sulfate and, after the desiccant had been filtered off, dried under reduced pressure. 100 mg of the title compound were obtained. LC-MS rt: 0.90 min [M+H]+: 264.2 (met. b)
