Reaction Conditions

Reaction Steps

To a mixture of 0.72 g of 3-bromopropanol, 1.0 g of 2,6-dichloro-4-(3,3-dichloro-2-propenyloxy)phenol, 3.0 g of hexane, 2.0 g of toluene, 0.06 g of tetra-n-butylammonium bromide and 5.0 g of water was added 0.77 g of a 27% aqueous sodium hydroxide solution. The mixture was heated to 60° C. and stirred for 4 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 1.2 g of 3-(2,6-dichloro-4-(3,3-dichloro-2-propenyloxy)phenoxy)-1-propyl alcohol (purity: 93%, yield: 90%).
