Reaction Steps

6-Chloro-N*7*,N*7*-diethyl-[1,2,4]triazolo[4,3-b]pyridazine-3,7-diamine (W2.021, 38 mg) were initially charged in ethanol (7 ml) and admixed with sodium ethoxide (24 mg). The reaction mixture stirred at RT for 4 h. It was then stirred at 45° C. for another 2 h. Subsequently, the mixture was dried, the residue was admixed with water and extracted three times with EA, and the combined EA phases were dried with magnesium sulfate, filtered and concentrated. 30 mg of the title compound were obtained as a crude product, which was clean enough for the next reaction.
