HCID 8028Tetrahydrofuran溶媒

実験手順

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).
