실험 절차

To a solution of 0.30 g of 2,6-dichloro-4-(3,3-dichloro-2-propenyloxy)phenol, 0.24 g of 3-(4-bromophenoxy)-1-propanol and 0.27 g of triphenylphosphine dissolved in 10 ml of tetrahydrofuran was added dropwise a solution of 0.21 g of diisopropylazodicarboxylate dissolved in 5 ml of tetrahydrofuran, while stirring at room temperature. After stirring at room temperature for 24 hours, the reaction mixture was concentrated to obtain a residue. The residue was subjected to silica gel chromatography, which afforded 0.34 g of 3,5-dichloro-1-(3,3-dichloro-2-propenyloxy)-4-(3-(4-bromophenoxy) propyloxy)benzene (65% yield), nD25.0 1.5917.
