Reaction Steps
To a solution of 4-bromo-1-fluoro-2-nitrobenzene (6 g, 27.27 mmol) in dichloromethane (100 ml) was added potassium carbonate (7.5 g, 54.27 mmol). This was followed by the addition of CH3NH2 (20 ml, 33% aqueous), which was added dropwise with stirring at room temperature. The resulting solution was stirred for 2 h at room temperature, extracted with dichloromethane (2×200 ml), and the organic layers combined and concentrated under vacuum to afford 4-bromo-N-methyl-2-nitroaniline as a red solid (6.1 g, 97%).
