Procedure

2-(5-Tetrazolyl)phenoxathiin (0.70g) and m-chloroperoxybenzoic acid (0.45g) were stirred for 2 hours at room temperature in acetone (20 ml.) and water (5 ml.). The reaction mixture was diluted with water, and the solid filtered, dried, washed with ether and re-dried to give 2-(5-tetrazolyl)phenoxathiin-10-oxide m.p. 267°-8° C. Recrystallisation from glacial acetic acid raised the melting point to 280°-1° C.
