Reaction Steps

1,6-naphthyridin-5-ol (1.00 g, 6.8 mmol), ethyl iodoacetate (1.6 ml, 14 mmol) and cesium carbonate (4.5 g, 14 mmol) were dissolved in 25 mL of THF then stirred and heated at 100° C. for 2 h until the reaction was complete. The reaction was concentrated and purified via MPLC using a gradient to 90% DCM: 10% MeOH to afford ethyl 2-(5-oxo-1,6-naphthyridin-6(5H)-yl)acetate (1.5 g, 94% yield).
