Procedure
A stirred suspension of 2,6-dinitroaniline (5 g, 27.3 mmol) in glacial acetic acid (50 ml) was treated, dropwise, with bromine (1.5 ml, 30 mmol) and heated at 120° C. for 2 h. After cooling to ambient temperature, the resultant mixture was poured into water (500 ml). The precipitated solid was collected by filtration, washed with water and dried in vacuo to give 4-Bromo-2,6-dinitroaniline as a yellow solid (6.5 g, 91%).
