Procedure
A mixture of 9.1 g of 2,6-dichloro-4-(3,3-dichloro-2-propenyloxy)phenol, 8.9 g of N-(4-bromoethyl)phthalimide, 4.4 g of potassium carbonate and 100 ml of N,N-dimethylformamide was stirred at room temperature for 24 hours. The reaction mixture was poured into ice water and made weak acidic by the addition of 10% hydrochloric acid, after which 200 ml of ethyl acetate was added for extraction. The ethyl acetate layer was successively washed with 10% hydrochloric acid and saturated saline solution, dried over anhydrous magnesium sulfate, and then concentrated to give crude crystals. The crude crystals were washed with n-hexane and then dried under reduced pressure, which afforded 14.5 g of 3,5-dichloro-4-(4-phthalimidobutyloxy)-1-(3,3-dichloro-2-propenyloxy)benzene (94% yield).
