반응 단계

To a mixture of 0.35 g of 4-(3-aminopropyloxy)-3,5-dichloro-1-(3,3-dichloro-2-propenyloxy)benzene, 0.19 g of 5-bromo-2-furancarboxylic acid, 0.18 ml of triethylamine and 10 ml of chloroform was added 0.23 g of WSC hydrochloride, while stirring at room temperature. After stirring at room temperature for 6 hours, the reaction mixture was concentrated to give a residue. The residue was dissolved in 50 ml of ethyl acetate, and the ethyl acetate layer was successively washed with 10% hydrochloric acid, saturated aqueous sodium hydrogen carbonate solution and saturated saline solution, dried over anhydrous magnesium sulfate, and then concentrated to give a residue. The residue was subjected to silica gel chromatography, which afforded 0.35 g of 3,5-dichloro-1-(3,3-dichloro-2-propenyloxy)-4-(3-(5-bromo-2-furancarboxamido)propyloxy)-benzene (64% yield), nD24.0 1.5918.
