To a solution of 5-(5-methyl-3-phenyl-isoxazol-4-ylmethoxy)-pyridine-2-carboxylic acid ethyl ester (481 mg, 1.42 mmol) in THF (12 mL) was added a solution of lithium hydroxide monohydrate (418 mg, 9.8 mmol) in water (6 mL) and the resulting mixture stirred at room temperature overnight. The mixture was acidified with HCl (1 N, 10 mL) and evaporation afforded the title compound (335 mg, 70%) which was obtained as a light yellow solid. MS: m/e=309.0 [M−H]−.
