反応手順

To a mixture of 0.35 g of 4-(3-aminopropyloxy)-3,5-dichloro-1-(3,3-dichloro-2-propenyloxy) benzene, 0.17 g of 4-chlorophenylacetic acid, 0.1 8 ml of triethylamine and 10 ml of dichloromethane 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-(4-chlorophenylacetamido )propyloxy)benzene (70% yield), m.p., 108.4° C.
