Reaction Steps

2-Chloro-4-iodoaniline (2 g, 7.9 mmol), 1,2,4-triazole (0.62 g, 9 mmol) and copper iodide (0.15 g, 0.79 mmol) in DMF (10 ml) were heated to 140° C. and stirred under dry nitrogen for 72 hours. The reaction was cooled to room temperature and diluted with ethyl acetate (50 ml). The organic layer was washed with water, brine, dried over sodium sulfate and filtered. The solvent was removed under vacuum and the residue purified by silica gel column chromatography eluting with 20% ethyl acetate in dichloromethane to give the title compound as a white powder (1.2 g, 78%). 1H-NMR (500 MHz, CDCl3): δ 4.43 (s, 2H), 6.76 (d, J=8.7 Hz, 1H), 7.23 (dd, J=2.5 Hz, 8.6 Hz, 1H), 7.48 (d, J=2.4 Hz, 1H), 7.94 (s, 1H), 8.36 (s, 1H).
