Versuchsvorschrift

To a 0° C. cooled stirred solution of 6-(3-fluorophenyl)pyrazin-2-ylamine (0.5 g, 2.64 mmol) in a mixture of DMSO (10 mL) and water (0.25 mL), was added N-bromosuccinimide (0.518 g, 2.90 mmol) in portions. After stirring for 5 h, the mixture was poured into water, the precipitate collected by filtration, washed with water and dried to give the title compound as a yellow solid (0.60 g, 85%).
