Since the temperature of reaction is not specified, I take the liberty to assume.Aniline reacting with sulfuric acid at 180 degrees to form sulfanilic acid. This sulfanilic acid if reacted with Bromine to give 2,6-Dibromosulfanilic acid which is hydrolysed in water containing some acid catalyst to give 2,6-Dibromo aniline.
This is the best possibility i can arrive at looking at your data.
