Morpholine → (5-(3-((7-Methoxyquinolin-4-yloxy)methyl)-[1,2,4]triazolo[4,3-b]pyridazin-6-yl)thiophen-2-yl)(morpholino)methanone

Participants

Reaction Steps

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 (5 mL) was added N-ethyl-N-isopropylpropan-2-amine (0.15 ml, 0.86 mmol) and morpholine (0.15 ml, 1.7 mmol). The solution was stirred at room temperature for two hours then was concentrated in vacuo. The brown residue was purified via MPLC chromatography (eluted with 0-5% methanol in dichloromethane) to yield the product as a tan solid. MS m/z=503.0 [M+1]+. Calc'd for C25H22N6O4S: 502.1.
