Reaction Steps

1,3,5-Trifluoro-2-nitrobenzene (3.0 g, 16.90 mmol) was dissolved in EtOH (29.7 mL) and Methylamine 40% in Water (1.44 mL, 17.80 mmol) was added dropwise at 0° C. The color went from bright yellow to an orange precipitate within 20 min. After 4 h at RT. 0.66 mL of Methylamine was added (9 mmol). To complete the reaction, an additional 0.26 ml (3.6 mmol) of Methylamine was added after 2 h at RT. The completion was achieved within 20 min. Water (75 mL) was added to the reaction mixture and the solid was isolated by filtration, washed with water (2*10 mL) and dried over high vacuum to afford 2.64 g of 3,5-difluoro-N-methyl-2-nitrobenzenamine (Yield: 83%) as an orange solid.
