Reaction Steps

1,4-Difluoro-2-nitrobenzene (2.63 g, 16.53 mmol) was dissolved in EtOH (9 mL) and Methylamine 40% in Water (9 mL) was added dropwise at 0° C. and the mixture was warming up to RT overnight. 75 mL of water was added to the reaction mixture and the orange solid was filtered and washed with water (2*10 ml) to afford 2.78 g of 4-fluoro-N-methyl-2-nitrobenzenamine (Yield: 99%) as an orange crystalline solid.
