A slurry of 6.14 g of 4-chloro-2-methylphenyl methyl sulfone, 8.35 g of 3,4-dichlorophenol and 7.08 g of K2CO3 in 150 ml of sulfolane was heated at 170° C. for 7 hrs. The product (6.3 g, 63.4% yield) was isolated from the reaction mixture essentially as described in Example 18. Recrystallization from ethanol afforded purified 4-(3-methyl-4-(methylsulfonyl)phenoxy)-1,2-dichlorobenzene, mp 154°-156° C.
