Reaction Steps

(6-Chloro-7,8-dimethyl-[1,2,4]triazolo[4,3-b]pyridazin-3-yl)(2,2,2-trifluoroethyl)amine (W2.150; 330 mg) was initially charged in ethanol (25 ml) and admixed with sodium ethoxide (90 mg). The reaction mixture was stirred at 50° C. for 4 h, then further sodium ethoxide (10 mg) was added and the mixture was stirred further at 50° C. for 3 h. After standing overnight, the mixture was admixed with water and dried. The residue was taken up in EA and washed three times with water. The EA phase was dried over sodium sulfate, filtered and concentrated. 340 mg of the title compound were obtained. LC-MS rt: 0.82 min [M+H]+: 290.2 (met. b)
