Reaction Conditions

Reaction Steps

A mixture of 0.53 g of 3-bromopropanol, 5.0 g of toluene and 0.06 q of tetra-n-butylammonium bromide was heated to 60° C. Thereto was added dropwise a mixed solution of 1.0 q of 2,6-dichloro-4-(3,3-dichloro-2-propenyloxy)phenol, 5.0 g of water and 0.16 g of lithium hydroxide monohydrate with stirring over 6 hours. After completion of the addition, the mixture was further stirred at 60° C. for 10 hours. The reaction mixture was then cooled to 20° C. After 2.0 g of a 20% aqueous sulfuric acid solution was added thereto, the mixture was stirred and then separated. The obtained organic layer was washed with 5.0 g of water and concentrated under reduced pressure to give 1.1 g of 3-(2,6-dichloro-4-(3,3-dichloro-2-propenyloxy)phenoxy)-1-propyl alcohol (purity: 93%, yield: 84%).
