A solution of 50 g (0.22 mol) of 2-nitro-4-trifluoromethyl-1-chlorobenzene, 22 g (0.22 mol) of cyclohexylamine and 61 g (0.44 mol) of potassium carbonate in 600 ml of ethanol was refluxed for 4 hours. The reaction mixture was concentrated and then the crude product was washed with water and ether. The organic phase was worked up, and the product was purified by column chromatography on silica gel (mobile phase: heptane/ethyl acetate=5/1).
