Reaction Steps
To dimethylformamide solution (364 ml) containing 2-chloro-5-nitrobenzonitrile (91 g) and neopentyl alcohol (52 g) was added sodium hydride (60% content, 27.8 g) under ice-cooling and the mixture was stirred for 1 h. The reaction mixture was poured into water and extracted with toluene. The organic layer was washed with saturated brine and dried over anhydrous magnesium sulfate, after which the solvent was evaporated under reduced pressure. Diisopropyl ether was added to the residue to allow crystallization. The crystals were recrystallized from a mixed solvent of ethyl acetate-n-hexane to give 5-nitro-2-neopentyloxybenzonitrile (105 g), melting point: 90–91° C.
