Participants

Reaction Steps

A suspension of 0.69 g. (0.029 moles) of 3-trifluoromethyl-4-aminobenzenesulfonamide in 7 ml. of water and 7 ml. of 48% hydrobromic acid is treated dropwise with 0.16 ml. of liquid bromine and stirred for 3 hours at room temperature. The reaction mixture is filtered, the solid material washed with 10% aqueous sodium bicarbonate, water and dried. The dried solid is recrystallized from toluene affording 0.76 g. of 4-amino-3-bromo-5-trifluoromethylbenzenesulfonamide, m.p. 248°-252° C.
