A mixture of 4-chloro-6-methoxy-7-hydroxy quinoline (0.63 g, 3.0 mmol) and N(3-hydroxypropyl)morpholine (0.54 g, 3.8 mmol) was treated with diethyl azodicarboxylate (1.38 g, 6.0 mmol) and triphenylphosphine (1.57 g, 6.0 mmol) at room temperature for 2 hours. Purification by flash chromatography on silica gel, eluting with 0-20% methanol in 1:1 ethyl acetate/dichloromethane yielded 4-Chloro-6-methoxy-7-(3-morpholinopropoxy)-quinoline (0.70 g, 69% yield) as white solid:
