実験手順
A solution of 2-(2-chloro-ethoxy)-6-nitro-phenylamine (30.0 g, 0.14 mol), N-chlorosuccinimide and acetonitrile (1.3 L) was refluxed for 4 hours. The mixture was concentrated under vacuum and the residue was diluted with ethyl acetate (500 ml). The organic layer was washed with water (2×250 ml) and brine (250 ml), dried over anhydrous magnesium sulfate and filtered. The solvent was removed under vacuum to give an orange solid residue. Crystallization from ethyl acetate-hexanes gave 33.5 g (95.3%) of product as an orange solid: mp 109-110° C.; MS (EI) 250/252/254 m/e (M+).
