Abstract
5-tetrazolyl compound which can be prepared from the process from the compound, with an alkali metal azide, such as potassium azide, sodium azide or the like in the presence of ammonium chloride. The reaction is carried out, appropriately, in the presence of a solvent such as a polar aprotic solvent, for example, dimethyl sulfoxide, dimethylformamide or the like. The desired tetrazolyl compound is then recovered following known procedures, for example, crystallization or the like. The process is hydrolyzed with a mineral acid such as hydrochloric acid.
