Boron tribromide → HCID 53663674, compound

Participants

Reaction Steps

To a solution of ether 6e (120 mg, 0.312 mmol) in CH2Cl2 (12 mL) at 0° C. was added 1M boron tribromide in CH2Cl2 (4 mL). The mixture was stirred for 1.5 h at room temperature and then quenched with ice/H2O. After stirring for 2 h, the mixture was extracted with CH2Cl2. The combined organic layers were washed with water and dried (MgSO4). The solvent was removed under reduced pressure and the residue chromatographed (silica gel, 10-20% methanol/CH2Cl2)to give phenol 6f as a white solid (45 mg, 39%): ESI m/z: 369 (M−H−, 100%).
