Reaction Steps
Sodium hydride (9.9 g, 0.414 mol, 95% dry) was added in portions to a stirred solution of benzyl alcohol (41.0 g, 0.394 mol) in THF (1.0 L) at room temperature under a nitrogen atmosphere and stirred for 1 h. To this solution was added dropwise 1,3-dibromo-5-fluorobenzene (100.0 g, 0.394 mol). After stirring overnight, the mixture was partitioned with H2O (600 mL) and EtOAc (4× 600 mL). The combined organic extracts were dried (Na2SO4), filtered and concentrated in vacuo. Flash chromatography on silica gel eluting with hexanes afforded the sub-title compound (101.3 g, 75%) as a yellow oil.
