実験手順
To a solution of 4-iodobenzenamine (2.38 g, 10.9 mmol) in MeCN (20 mL) at 0° C. was added tert-butyl nitrite (1.95 mL, 1.69 g, 16.4 mmol) and azidotrimethylsilane (1.70 mL, 1.49 g, 12.9 mmol). The reaction mixture was warmed to room temperature and stirred for 6 h, heated to 40° C. for 18 h, and diluted with EtOAc. The aqueous phase was washed with water (2×), brine (1×), dried over MgSO4, filtered, and concentrated to give 1-azido-4-iodobenzene which was used in the next step without further purification.
