Procedure

Potassium carbonate (6.0 g, 43.5 mmol) and N-methylcyclohexylamine (4.6 g, 40.6 mmol) were added to a N-methylpyrolidone (NMP) solution (20 ml) of 2,5-difluoronitrobenzene (5.0 g, 31.4 mmol), and stirred at 100° C. for 3 hours. The reaction mixture was cooled to room temperature, water was added, and the resulting mixture was extracted with ethyl acetate. The organic layer was washed with water, and then dried over anhydrous magnesium sulfate. The resulting dry product was concentrated under reduced pressure to thereby obtain 7.0 g of oily yellow N-cyclohexyl-4-fluoro-2-nitro-N-methylaniline (yield: 89%).
