Reaction Steps

A solution of 6-chloro-3-(trifluoromethyl)-[1,2,4]triazolo[4,3-b]pyridazine (50 mg, 0.22 mmol) in ethanol (1 mL) was added to 3-(4-methoxyphenyl)pyrrolidine hydrochloride (71 mg, 0.33 mmol). The reaction mixture was treated with DIPEA (86 mg, 0.66 mmol) and the mixture was heated at 70° C. for 16 hours. The reaction mixture was evaporated to leave an involatile residue that was purified by preparative reverse phase chromatography to give 6-[3-(4-methoxyphenyl)pyrrolidin-1-yl]-3-(trifluoromethyl)[1,2,4]triazolo[4,3-b]pyridazine (45 mg, 55%).
