실험 절차

A mixture of 8.9 g (36.2 mmole) 3-bromo-9H-carbazole, 10.6 g (36.2 mmole) of 2-iododibenzo[b,d]furan, 17.1 g (90 mmole) of copper(I) iodide, 19.1 g (90 mmole) of potassium phosphate, 10.3 g (90 mmole) of trans-1,2-cyclohexanediamine and 1,4-dioxane 700 ml were refluxed under nitrogen for about overnight. Then, the solution was filtered at 110° C. To receive the filtrate, And the 1,4-dioxane was removed under reduced pressure from the filtrate. The filtrate was extracted with 500 ml dichloromethane and 2000 ml water, the organic layer was dried with anhydrous magnesium sulfate, the solvent was removed and the residue was purified by column chromatography on silica (hexane-ethyl acetate) to give product 8.4 g (56%).
