Procedure

To a solution of 5-(3-((7-methoxyquinolin-4-yloxy)methyl)-[1,2,4]triazolo[4,3-b]pyridazin-6-yl)thiophene-2-carbonyl chloride (0.260 g, 0.58 mmol) in dichloromethane was added N-ethyl-N-isopropylpropan-2-amine (0.20 ml, 1.2 mmol) and dimethylamine (1.4 ml, 2.9 mmol). The solution was stirred at room temperature for one hour then was concentrated in vacuo. The residue was triturated with water and filtered; the resulting precipitate was triturated with acetonitrile and filtered to yield the product as an off-white solid. MS m/z=461.0 [M+1]+. Calc'd for C23H20N6O3S: 460.1.
