Versuchsvorschrift

To a solution of aluminum chloride (0.2 g) in anisole (1 ml) cooled at 0° C. is added a solution of 1-(2-t-butoxyethyl)-1H-tetrazole-5-thiol (0.202 g) in dichloromethane (2 ml), and the mixture is stirred at room temperature for 3 hours. The reaction mixture is poured into a mixture of 3N-hydrochloric acid (10 ml) and ethyl acetate (20 ml), shaken and the resulting organic layer is taken up. The layer is extracted with aqueous 5% sodium hydroxide. The extract is acidified with hydrochloric acid and extracted again with ethyl acetate. The extract is concentrated under reduced pressure to give 1-(2-hydroxyethyl)-1H-tetrazole-5-thiol. mp. 135°-136° C.
