Reaction Steps

N,N-Diethyl-3-amino-6-chloro-[1,2,4]triazolo[4,3-b]pyridazine-7-carboxamide (W2.019, 50 mg) was initially charged in ethanol (5 ml) and admixed with sodium ethoxide (28 mg) while stirring. After stirring at RT for 7 h and leaving to stand overnight, the solvent was drawn off and the mixture was 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. 51 mg of the title compound were obtained.
