This compound was prepared in a manner analogous to that set forth in Step E of Example 1, using 25.3 grams (0.086 mole) of 4-(2,6-dichloro-4-hydroxyphenoxy)butyl acetate, 19.5 grams (0.1 mole) of 1,1,1,3-tetrachloropropane, and 18 grams (0.13 mole) of potassium carbonate in 250 mL of DMF was heated at 80° C. during a 16 hour period. The crude reaction product was purified with column chromatography on silica gel using 1:1 methylene chloride:hexane as an eluant. The appropriate fractions were combined and concentrated under reduced pressure, yielding 27.1 grams of the subject compound. The NMR spectrum was consistent with the proposed structure.
