Reaktionsschritte
4-Bromo-1-fluoro-2-nitrobenzene (1.50 g, 6.82 mmol) and K2CO3 (1.88 g, 13.6 mmol) were suspended in DCM (7 mL). MeNH2 (40% in H2O, 7 mL) was added slowly and the mixture stirred at room temperature for 4 h. The mixture was diluted with H2O and extracted with DCM (3×40 mL). The combined DCM layers were washed with brine, dried (MgSO4), filtered and concentrated to afford the product as a bright orange solid (1.47 g, 93%).
