Procedure

To a solution of methyl[6-(1H-tetrazol-1-yl)pyridin-2-yl]acetate (367 mg, 1.67 mmol) in THF (5 mL) was added 1.5 mL of 1N aqueous lithium hydroxide solution. The reaction mixture was allowed to stir at ambient temperature for 30 minutes and then concentrated in vacuo. The crude residue was dissolved in 4 mL of a 1N aqueous hydrochloric acid solution and extracted with DCM (3×20 mL). The combined organic layers were then dried over sodium sulfate, filtered and concentrated in vacuo to afford crude title compound which was used without further purification. LC/MS (M+H-28)+178.
