Procedure

To a solution of 9.09 g (0.0558 mole) of 3,4-dichlorophenol dissolved in 150 ml of DMSO was added 2.23 g (0.0558 mole) of NaOH. The mixture was heated to 60° C. and 11.3 g (0.0502 mole) of 3,4-dichlorophenyl methyl sulfone was added and the mixture heated at 150° C. for 3.75 hrs. The mixture was cooled and poured into water. The crystalline product was collected by filtration, washed with water and dried, which gave 14.5 g (82.4% yield) of product. Recrystallization from ethanol afforded purified 4-(2-chloro-4-(methylsulfonyl)phenoxy)-1,2-dichlorobenzene, mp 102°-104° C.
