실험 절차

To a slurry of 10.0 g (0.0350 moles) of 2-(4-(methylthio)phenoxy)-5-nitrobenzonitrile in 75 ml of glacial acetic acid heated at 60° C. was added 15.85 g of aqueous 30% hydrogen peroxide (0.140 moles) over 5 minutes. An additional 25 ml of glacial acetic acid was added and the mixture heated at 75° C. for 3 hrs. The reaction mixture was cooled and poured into water. The product was collected by filtration, washed with water and dried to obtain 10.9 g of product (98.2% yield), mp 205°-206.5° C. Recrystallization from methanol gave purified 2-(4-(methylsulfonyl)phenoxy)-5-nitrobenzonitrile, mp 206°-207° C.
