Procedure
N,N-Dimethylpropane-1,3-diamine (4.90 ml, 39 mmol) and potassium carbonate (6.37 g, 46 mmol) were added to 1-fluoro-4-nitrobenzene (5.0 g, 35 mmol) and the mixture was heated at 70° C. for 3 hours. Insoluble material was removed by filtration and the filtrate was concentrated. The residue was dissolved in ethyl acetate (100 ml) and the solution was washed with water (3×100 ml) and saturated sodium chloride (100 ml) and dried. The solvent was removed by evaporation to give the product as a yellow oil (8.57 g). MS (MH+): 248.
