実験手順

2.12 g of 5-(tetrazol-1-yl)-valeric acid ethyl ester are dissolved in 5 ml of methanol, and 4.28 ml of a methanolic NaOH solution (3N) are added thereto. After stirring for 2.5 hours at room temperature, the solvent is distilled off and the residue is taken up in water. After washing with ethyl acetate, the aqueous phase is acidified (pH 3) and extracted twice with ethyl acetate. After drying and concentrating by evaporation, the pure title compound is obtained.
