Reaction Steps
To a solution of tert-butyl 2-(2-(3-azidopropyl)-5-(2,5-difluorophenyl)-2-phenyl-1,3,4-thiadiazol-3(2H)-yl)-6,7-dihydrothiazolo[5,4-c]pyridine-5(4H)-carboxylate (0.313 g, 0.524 mmol) in 10.0 mL of DCM at 0° C. was added TFA (1 mL). The mixture was stirred for 1 hour at 0° C. then at room temperature for 1 hour. The reaction was then concentrated to dryness and partitioned between EtOAc (30 mL) and saturated NaHCO3 solution (30 mL). The aqueous layer was extracted with EtOAc (2×20 mL) and the combined organic phases were washed with brine (20 mL), dried over Na2SO4 and concentrated in vacuo to afford the desired product as a yellow gum (0.251 g, 96%).
