실험 절차

Tetrazole-5-carboxylic acid can be prepared by treating ethyl cyanoformate with sodium azide and ammonium chloride to form ethyl tetrazole-5-carboxylate, which is hydrolyzed with alkali (e.g., KOH) to give alkali tetrazole-5-carboxylate, according to the method described in J. Med. Chem. 19, 289(1976) and Ibid, 29, 538(1986).
