Reaction Conditions

Reaction Steps

A solution of (2-bromophenyl)acetic acid (100 g, 0.46 mmol) in dry THF (2 L) was added NaBH4 (29 g, 0.77 mol) in portions. The contents were cooled to 0° C., and BF3. Et2O (123 mL, 0.77 mol) was added drop wise over 1 h. The mixture was allowed to warm to 25° C. and stirred for 16 h. The reaction was cooled to 0° C. and cautiously quenched with aqueous sodium hydroxide. The contents were stirred for 3 h, and then extracted with EtOAc. The organic layer was dried and concentrated to give 2-(2-bromophenyl)ethanol.
