Reaction Steps
To a solution of 2-bromo-6-hydroxybenzaldehyde (3.8 g, 18.91 mmol, 1 eq.) in a mixture of THF and MeOH (4/1, 25 mL) was added NaBH4 (1.4 g, 37.81 mmol, 1.5 eq.) at rt portion-wise. Upon the completion of addition, the mixture was continued to stir at rt for 30 min. The mixture was quenched with HCl (4 N) and extracted with EtOAC twice. The combined organic layer was dried over Na2SO4, concentrated, and purified on silica gel using 25% EtOAc/hexanes as eluent to give 3-bromo-2-(hydroxymethyl)phenol (2.3 g, 60%) as a colorless oil.
