Reaction Steps

6-Chloro-8-ethyl-[1,2,4]triazolo[4,3-b]pyridazin-3-ylamine (W2.003; 700 mg) was dissolved in ethanol (100 ml) while stirring. Thereafter, the reaction mixture was admixed with sodium ethoxide (724 mg) and stirred at RT for 2 h. Subsequently, the mixture was heated to 45° C. for 3 h. After the solvent had been drawn off, 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. 670 mg of the title compound were obtained.
