反応手順
A 100 mL 3-neck flask was charged with copper iodide (0.057 g, 0.301 mmol), 2-bromo-9H-carbazole (7.4 g, 30.1 mmol), 2-iodopyridine (12.3 g, 60.1 mmol), potassium phosphate (12.8 g, 60.1 mmol), (1R,4R)-cyclohexane-1,4-diamine (0.343 g, 3.0 mmol), and dioxane (25 mL) and the reaction mixture was heated at 65° C. for 16 hours. The reaction mixture was then poured into deionized water and extracted with dichloromethane The organic layers were combined and subjected to a column chromatography (neutral Al2O3, 99/1 hexane/EtOAc) to yield 4.2 g (43%) of 2-bromo-9-(pyridin-2-yl)-9H-carbazole as a white solid. The product was confirmed by GC/MS and NMR.
