To a solution of 2-([1,2,4]triazolo[4,3-a]pyridin-3-yl)-8-(tert-butyldimethylsilyloxy)quinoline (18.92 g, 50.25 mmol) in anhydrous THF (400 mL) at 0° C. was added tetrabutylammonium fluoride (75.4 mL, 1.0 M/THF, 75.4 mmol). After stirring for 1 hour at this temperature the mixture was partitioned between saturated NaHCO3 and EtOAc. The aqueous phase was extracted with EtOAc and the combined organic phases were washed with brine, dried over Na2SO4, filtered and concentrated under reduced pressure. The residue was triturated with CH2Cl2, filtered and dried in vacuo to provide 11.91 g (90%) of desired product as a beige solid.
