Mode opératoire

3-Cyanothianthrene-5,5-dioxide (0.55g), sodium azide (0.36g), ammonium chloride (0.30g) and dimethylformamide (15 ml) were heated together at 130°-135° C. for 3 hr. The mixture was cooled, poured into dilute hydrochloric acid, and the oily precipitated product extracted into chloroform and washed with water. On standing, 3-(5-tetrazolyl)thianthrene-5,5-dioxide crystallised out, m.p. 233° C. (decomposition).
