A new method for synthesizing the tetrazole derivatives from secondary amines through cyanation/tetrazolation has been developed. Trichloroacetonitrile is used as the cyano source to synthesize N-nitrile instead of highly toxic and expensive cyanogen bromide. In this protocol, the reaction of secondary amines with various substituents proceed smoothly, and the desired tetrazole derivatives are obtained directly in fair to high yields without isolation of intermediate cyanamides.
