Reaction Steps

51.5 g (0.27 mol) of 2,5-dichloronitrobenzene, 22.3 g (0.27 mol) of cyclohexylamine, 74.6 g (0.54 mol) of potassium carbonate and 0.5 g of 18-crown-in 300 ml of dimethylformamide were heated at 100° C. for 4 h. The mixture was then poured into water and extracted with ethyl acetate. The organic phase was dried and concentrated under reduced pressure. The residue was recrystallized from i-propanol, resulting in 42.3 g (62%) of the product. Melting point 101°-103° C.
