Procedure

N-Bromosuccinimide (160.4 g, 0.90 mol) was added in small portions to a stirred, cooled solution of 2-fluoroaniline (100.0 g, 0.90 mol) in dry dichloromethane (400 ml). The stirred mixture was allowed to warm to 0° C. over 45 min, washed with water and dried (MgSO4). The solvent was removed in vacuo to yield a red solid (180 g) which was steam distilled to give a colourless solid.
