To 2-fluoro-5-(3-(oxazol-5-yl)pyridin-2-yloxy)benzoic acid (196 mg, 0.653 mmol) in CH2Cl2 (6.0 mL) was added oxalyl chloride (0.28 mL, 3.3 mmol) followed by DMF (2 drops). The mixture was stirred under nitrogen at rt for 15 hours. The reaction was concentrated to yield 2-fluoro-5-(3-(oxazol-5-yl)pyridin-2-yloxy)benzoyl chloride, which was used without further purification.
