(57) [Summary] (Modified) [Objective] The use of alkylamine salts as a catalyst in the reaction of the nitriles of the present invention with an alkali metal azide provides high yield and high purity of 5- (1,1 '). Preparation of -biphenyl) -1H-tetrazole. [Structure] 5- (1,1'-biphenyl) -1 from biphenyl-2-carbonitriles and alkali metal azides by using alkylamine salts as a catalyst A method for producing H-tetrazole. [Effects] The tetrazole produced according to the present invention has a fast reaction rate at about the reflux temperature, is produced in a short time with high yield and high purity, has high production efficiency, and can be economically and industrially produced.
