By heating an N-(2-hydroxyethyl)dithiocarbamate ester protected at its hydroxy group as an ether in the presence of an azide, the corresponding 1-(protected hydroxyethyl)-1H-tetrazole-5-thiol is obtained, and then, if required, deprotecting the etheric protection to give an industrially useful chemical, 1-(2-hydroxyethyl)-1H-tetrazole-5-thiol.
