Procedure

57.6 g (0.3 mol) of 2,5-dichloronitrobenzene, 26.2 g (0.3 mol) of 2,2-dimethylpropylamine, 82.9 g (0.6 mol) of potassium carbonate and 0.5 g of sodium iodide in 400 ml of dimethylformamide were heated at 80° C. for 10 h. The mixture was then added to a large amount of water and extracted with ethyl acetate. The organic phase was dried and concentrated under reduced pressure. The residue was purified by chromatography on silica gel (mobile phase: petroleum ether/toluene=16/1) to yield 32.3 g (50%) of the product. Melting point 78° C.
