Procedure

Sodium hydride (60%; 432 mg; 10.8 mmol) was suspended in DMF (5 mL) and cooled to 0° C. under inert atmosphere. 4-Iodobenzyl alcohol (2.53 g; 10.8 mmol) was dissolved in DMF (5 mL) and added dropwise to the sodium hydride mixture. The solution was allowed to warm to room temperature and stirred for 15 minutes. The solution was then cooled to 0° C. 2,6-Difluorobenzonitrile (1 g; 7.2 mmol) in DMF (20 mL) was added dropwise to the alcohol solution and stirred for 2 hours. The solution was poured over 100 mL of cooled water. The solution was cooled for 1 hour and a precipitate was evident. The solid was collected by vacuum filtration and washed with water. Purification by recrystallization in cyclohexane yielded 1.49 grams of 2-fluoro-6-(4-iodobenzyloxy)benzonitrile.
