실험 절차

To a mixture of 2.30 g of 4-(2,2-diethoxyethoxy)butanol, 2.94 g of 2,6-dichloro-4-(3,3-dichloro-2-propenyloxy)phenol, 2.94 g of triphenylphosphine, and 30 ml of tetrahydrofuran was slowly added dropwise 2.48 g of diisopropylazodicarboxylate with stirring in a stream of nitrogen gas under ice cooling. After stirring at room temperature for 24 hours, the reaction mixture was concentrated to give a residue. This residue was subjected to silica gel chromatography, which afforded 4.48 g (yield, 73%) of 3,5-dichloro-1-(3,3-dichloro-2-propenyloxy)-4-(4-(2,2-diethoxyethoxy)butyloxy)benzene.
