3-Chloro-4-nitrobenzonitrile → 3-(2,4-Difluorophenylthio)-4-nitrobenzonitrile

Participants

Reaction Steps

A solution of potassium 2,4-difluorothiophenoxide (6.1 g) in methanol (30 ml) was added dropwise to a solution of 3-chloro-4-nitrobenzonitrile (5 g) in toluene (50 ml). The mixture was stirred for 5 hours at room temperature, washed with water, and concentrated to dryness. The oily residue was crystallized from a mixture of ethanol and hexane to give crystals of 3-(2,4-difluorophenylthio)-4-nitrobenzonitrile (3.6 g).
