実験手順

7.0 G. of 4-amino-3-nitrobenzenesulfonamide is suspended in 150 ml. of methanol at room temperature and brominated with 5.2 g. of liquid bromine added dropwise over 15 minutes. The reaction mixture is filtered and the solid material recrystallized from isopropanol affording 4-amino-3-bromo-5-nitrobenzenesulfonamide, m.p. 216°-218° C.
