Procedure

6-Amino-3-ethoxybenzoisothiazole-1,1-dioxide (D.3b) (0.25 g) was diazotised with sodium nitrite (0.21 g) in conc. sulphuric acid (5 ml) at 0°-10° C. for 2 h. After pouring into an aqueous (50 ml) solution of potassium iodide (1 g), the black suspension was treated with sodium metabisulphite until an orange precipitate remained. The solid was collected, washed with water and dried (0.26 g, mp 185°-90°)
