Versuchsvorschrift
A mixture of 4-bromo-2-fluoro-nitrobenzene (6 g, 27.3 mmol), methylamine (2M in MeOH, 34.1 mL, 68.2 mmol, 2.5 eq) and EtOH (80 mL) is stirred for 15 h at 85° C., allowed to cool and concentrated. The residue purified by trituration to afford 6 g of the title compound as an yellow solid: tR=5.13 min (System 1).
