Procedure

A solution of lithium hydroxide monohydrate (40 mg, 0.96 mmol) in water (1.2 mL) was added dropwise to a suspension of 6-(3-methyl-5-phenyl-3H-[1,2,3]triazol-4-ylmethoxy)-nicotinic acid methyl ester (156 mg, 0.96 mmol) in THF (1.2 mL) and MeOH (0.3 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 (129 mg, 86%) as a white solid. MS: m/e=309.4 [M−H]−.
