Reaction Steps
A solution of lithium hydroxide monohydrate (59 mg, 1.41 mmol) in water (1.8 mL) was added dropwise to a suspension of 5-[5-(5-fluoro-pyridin-2-yl)-3-methyl-3H-[1,2,3]triazol-4-ylmethoxy]-pyridine-2-carboxylic acid ethyl ester (252 mg, 0.71 mmol) in THF (1.8 mL) and MeOH (0.4 mL). The reaction mixture was then stirred at room temperature for 2 h. The reaction mixture was then evaporated and the residue dissolved in water, acidified with HCl (1N), and the resulting precipitate filtered off to afford the title product (180 mg, 78%) as a white solid after trituration with ethyl acetate. MS: m/e=330.1 [M+H]+.
