Procedure

A mixture of 4-(1H-tetrazol-5-yl)-cyclohexanecarboxylic acid methyl ester (304 mg, 2.74 mmol), lithium hydroxide (121 mg 2.89), THF and water were stirred at RT overnight. The reaction was concentrated and diluted with water acidified with concentrated HCl to pH 1 and extracted with ethyl acetate to give 4-(1H-tetrazol-5-yl)-cyclohexanecarboxylic acid (173 mg, 61%) as an off white solid. LCMS calcd C8H12N4O2 (m/e) 196, obsd 197 (M+H).
