実験手順: To a solution of 0.92 g of 4-fluoro-3-nitro-benzoic acid methyl ester in 15 ml of abs. DMF was added 0.84 ml of DIPEA, followed by 0.85 g of 2-(trifluoromethyl)cyclohexylamine. After 16 h at rt, the mixture was poured into water, the pH was adjusted to 4 by the addition of 1 M aqueous hydrochloric acid, and the reaction mixture was extracted with ethyl acetate three times. The combined organic phases were washed with water, dried over sodium sulphate and concentrated to yield 1.62 g (100%) of 3-Nitro-4-(2-trifluoromethyl-cyclohexylamino)-benzoic acid methyl ester. the reaction mixture was extracted with ethyl acetate three times The combined organic phases were washed with water dried over sodium sulphate concentrated
