20% Hydrochloric acid (30 ml) is added to methyl 4-(5-methyl-1,2,3,4-tetrazol-1-yl)butyrate (5.5 g) and the mixture is refluxed for 2 hour. The mixture is concentrated to dryness under reduced pressure. Acetone and benzene are added to the residue and water is removed by azeotropic distillation to obtain 4-(5-methyl-1,2,3,4-tetrazol-1-yl)butyric acid (4.7 g) as colorless liquid.
