실험 절차

To a slurry of 10.0 g (0.0350 moles) of 2-(4-(methylthio)phenoxy)-5-nitrobenzonitrile in 100 ml of glacial acetic acid was added a solution of 4.0 g of aqueous 30 percent (30%) hydrogen peroxide (0.0350 moles) dissolved in 20 ml of glacial acetic acid over 5 minutes. The reaction mixture was stirred at room temperature for 16 hrs and heated at 50° C. for 3 hrs. The reaction mixture was poured into water and the product collected by filtration, washed well with water and dried to obtain 9.8 g of product (92.8% yield). Recrystallization from ethanol afforded purified 2-(4-(methylsulfinyl)phenoxy)-5-nitrobenzonitrile, mp 159°-160° C.
