Procedure

3-Cyanothianthrene-5,5-dioxide (0.55 g), sodium azide (0.36 g), ammonium cloride (0.30 g) 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).
