Reaction Steps

To a suspension of 2-{2-[3-(5-fluoro-pyridin-2-yl)-5-methyl-isoxazol-4-yl]-ethyl}-4-methyl-thiazole-5-carboxylic acid methyl ester (1.02 g, 2.82 mmol) in THF (7 mL), water (7 mL) and MeOH (1.4 mL) was added lithium hydroxide monohydrate (237 mg, 5.65 mmol) and the resulting mixture stirred at room temperature overnight. The mixture was then evaporated to half volume and then acidified to pH 1 with HCl (1 N) and cooled to 0° C. for 15 min. A solid precipitated and was filtered off and dried to afford the title compound (867 mg, 88%) which was obtained as an off white solid. MS: m/e=346.2 [M−H]−.
