A total of 50.7 g (0.375 mol) of 4-fluorophenyl-acetonitrile is slowly added to a vigorously stirred, room-temperature solution of 150 g (3.75 mol) of sodium hydroxide in 750 ml of absolute methanol. After solution is complete, 46 g (0.374 mol) of nitrobenzene is slowly added. The resulting solution is warmed to 65°-70° C. and held at this temperature for 9 hours. The dark slurry is cooled to room temperature, diluted with 250 ml of 50% methanol, and cooled in an ice bath. The resulting dark precipitate is filtered and washed with cold methanol until the methanol washings were clear. The product (16) is recrystallized from toluene.
