実験手順
A mixture of 4-chloro-2-nitroaniline (5.5 g), bromobenzene (20 ml), potassium carbonate (1.63 g) and copper(I) iodide (0.68 g) was heated to 180° for 36 h. The reaction mixture was cooled to room temperature, then ethyl acetate (200 ml) and water (300 ml) were added; the organic extracts were washed with brine (2×150 ml), dried and concentrated in vacuo to give the crude compound which was purified by flash chromatography (eluting with CH-EA 95:5) to give the title compound (3.67 g). T.l.c. CH-EA (1:1 ), Rf 0.71.
