Participants

Reaction Steps

Ethyl 4-[(5-chloro-6-isobutoxypyridin-3-yl)oxy]-2,5-difluorobenzoate (Preparation 38, 150 mg, 0.389 mmol) and lithium hydroxide (250 mg, 10.44 mmol) were dissolved in water (2.5 mL) and THF (2.5 mL) and stirred at room temperature for 72 hours. The reaction mixture was concentrated in vacuo. The residue was dissolved in EtOAc (10 mL), washed with water (10 mL) and aqueous HCl (2 M, 10 mL), then was dried over sodium sulfate, filtered and concentrated in vacuo to yield the title compound as a white solid (140 mg, 100%):
