Reaction Steps
A mixture of 2-chloro-6-cyanothioxanthene (1.38g.), sodium azide (0.71g.), ammonium chloride (0.59g.) and dimethylformamide (20 ml.) was heated at 130° C. for 7 hr. The mixture was cooled, poured into cold dilute hydrochloric acid, and the precipitated product filtered off. Recrystallisation from acetic acid yielded 7-chloro-3(5-tetrazolyl)thioxanthene, which was dired at 154° C./20mm Hg., m.pt. 257° C. with decomposition.
