반응 단계
2-cyanophenoxathiin (2.25g), sodium azide (0.68g) ammonium chloride (0.59g) and dimethylformamide (30 ml.) were heated for 9 hours at 130° C. The solution was poured onto ice and 2 Normal sodium hydroxide solution, and extracted with chloroform. The aqueous phase was acidified with concentrated hydrochloric acid. The solid was filtered, washed and dried to give 2-5-tetrazolyl)phenoxathiin m.p. 210°-2° C. Recrystallisation from glacial acetic acid raised the melting point to 220°-1° C.
