Reaction Conditions

Reaction Steps

To a solution of 11.4 g (0.0575 moles) of 4-hydroxybenzophenone dissolved in 150 ml of DMSO was added 2.3 g (0.0575 moles) of NaOH. The mixture was heated to 60° C. and 10.0 g (0.0548 moles) of 2-chloro-5-nitrobenzonitrile was added and the mixture heated at 75° C. for 3 hrs. The reaction mixture was cooled and poured into a solution of 100 ml of 2 N aqueous NaOH and 700 ml of water. The product was collected by filtration, washed well with water and dried to obtain 17.75 g of product (89.6% yield). Recrystallization from a mixture of ethanol and dimethylformamide and a second recrystallization from chloroform afforded purified 2-(4-benzoylphenoxy)-5-nitrobenzonitrile, mp 179.5°-180.5° C.
