Reaction Steps
To a cold (ice water) suspension of sodium hydride (316 mg; 7.9 mmol) in anhydrous DMF (10 mL) is added a solution of 4-bromobenzyl alcohol (1.48 g; 7.9 mmol) in anhydrous DMF (5 mL) over 10 minutes. After allowing to room temperature over 30 minutes, this solution is added to a cold (ice water) stirred solution of 2,6-difluorobenzonitrile (1 g; 7.2 mmol) in anhydrous DMF (15 mL), and allowed to room temperature over 3 hours. The reaction mixture is poured into ice water with vigorous stirring and refrigerated overnight. The resulting precipitate is removed by filtration and dried under vacuum at 30° C. overnight to give 1.82 grams 2-(4-bromobenzyloxy)-6-fluorobenzonitrile.
