To a solution of 5.0 g (0.0307 moles) of 2,4-dichlorophenol dissolved in 150 ml of DMSO was added 1.23 g (0.0307 moles) of NaOH. The slurry was heated at 60° C. for 15 minutes and 5.04 g (0.0276 moles) of 2-chloro-5-nitrobenzonitrile was added. The mixture was heated at 75° C. for 3.25 hrs. The reaction mixture was cooled and poured into water. The product was collected by filtration, washed well with water and dried, yielding 8.1 g of product (95.3% yield). Recrystallization from ethanol afforded purified 2-(2,4-dichlorophenoxy)-5-nitrobenzonitrile, mp 153.5°-154.5° C.
