Versuchsvorschrift

The crystalline product obtained in (c) is dissolved in as small an amount of tetrahydrofuran as possible and the solution is added dropwise to 20 ml of 25% aqueous ammonia solution. After the reaction mixture has been stirred for 30 minutes it is poured into a mixture of ice and 10% hydrochloric acid. Extraction with ether yields 0.3 g of 6-bromo-8-sulfamoyl-2,2-dioxo-1,2-benzoxathiine of m.p. 224°-228° C. (decomposition with black colouration).
