Reaction Steps

To a dimethylformamide solution (30 ml) containing 2-chloro-5-nitrobenzonitrile (10 g) and phenol (5.7 g) was added sodium hydride (60% content, 2.63 g) under ice-cooling, and the mixture was stirred for 1 h. The reaction mixture was added to water and extracted with toluene. The organic layer was washed saturated brine and dried over anhydrous sodium sulfate, after which the solvent was evaporated under reduced pressure. The residue was recrystallized from diisopropyl ether to give 5-nitro-2-phenoxybenzonitrile (10.8 g), melting point: 126° C.
