実験手順

To a mixture of 9.27 g of 3,5-diethyl-1-(3,3-dichloro-2-propenyloxy)-4-(4-(2,2-diethoxyethoxy)butyloxy)benzene, 25 ml of acetic acid, and 5 ml of water was added 1 ml of concentrated hydrochloric acid at room temperature. After stirring at room temperature for 30 minutes, the reaction mixture was poured into water, and extracted twice with diethyl ether. The diethyl ether layers were combined, washed with water, aqueous sodium hydrogencarbonate solution, and aqueous sodium chloride solution in this order, dried over anhydrous magnesium sulfate, and concentrated, which afforded 7.62 g (yield, 98%) of 4-(2,6-diethyl-4-(3,3-dichloro-2-propenyloxy)phenoxy)butyloxyacetaldehyde.
