Reaction Steps

2-([1,2,4]triazolo[4,3-a]pyridin-3-yl)-6-fluoro-8-(triisopropylsilyloxy)quinoline (5.00 g, 11.5 mmol) was dissolved in 250 mL of anhydrous THF, followed by cooling to 0° C., then addition of TBAF (4.49 g, 17.2 mmol). Following 1 hour, the reaction was complete by TLC, and the crude reaction partitioned between water and ethyl acetate. The crude work-up was then filtered through standard filter paper with ethyl acetate wash, affording the desired product 2-([1,2,4]triazolo[4,3-a]pyridin-3-yl)-6-fluoroquinolin-8-ol (2.8 g, 9.99 mmol, 87% yield) as a white solid.
