A solution of 2-cyano-acetanilide (0.801 g, 5.0 mmol) and tri-n-butyltin azide (2.05 mL, 7.5 mmol) in anhydrous toluene (10 mL) was heated at reflux for 48 hrs. The mixture was allowed to cool to room temperature and treated with 2.0 N HCl in Et2O (5.0 mL). The resulting precipate was collected by suction, washed with hexane and dried in vacuo to give 2-(1H-tetrazol-5-yl)acetanilide (0.917 g, 90%) as a white solid.
