Participants

Reaction Steps

4-(3-(4-Chlorophenoxy)propyloxy)-3,5-dichlorophenoxyacetaldehyde diethylacetal (manufactured in Production Example 1 of intermediate described hereinafter) (1.6 g) was added dropwise to a mixed solution of 1 ml of hydrochloric acid and 9 ml of acetic acid with stirring at room temperature. After stirring at room temperature for 30 minutes, the reaction solution was poured into iced water and extracted twice with 100 ml of diethyl ether. The ether layers were combined. washed with water, washed twice with aqueous 5% sodium hydrogencarbonate, washed with water, dried over anhydrous magnesium sulfate and then concentrated to obtain 0.8 g of 4-(3-(4-chlorophenoxy)propyloxy)-3,5-dichlorophenoxyacetaldehyde as a crude product.
