Reaction Steps
tert-Butyl 4-[(5-chloro-6-isopropoxypyridin-3-yl)oxy]-3,5-difluorobenzoate (Preparation 145, 426 mg, 1.06 mmol) and LiOH (100 mg) were added to a solution of THF:water (1:1) and heated at 50° C. for 3 hours. The reaction was then quenched with aqueous 1M HCl and extracted with EtOAc. The combined organics were dried and concentrated in vacuo to afford the title compound as a white solid (342 mg, 94% yield):
