실험 절차
Then, a mixture of 15 g of the cis-1,4-bis(methanesulfonyloxy)-2-butene, 10 g of 3-bromoaniline, 24 g of anhydrous potassium carbonate and 70 ml of N,N-dimethylformamide was stirred at room temperature overnight. The reaction mixture was extracted with ethyl acetate-water, and the organic layer was washed with water and brine, dried over anhydrous magnesium sulfate and then evaporated. The residue was purified by silica gel column chromatography with 5% ethyl acetate/hexane, to give 6.6 g of the title compound.
