Versuchsvorschrift

To a flask containing BBr3 (1 M in CH2Cl2, 17 mL) at 0° C. was added a solution of 3-bromo-6-methoxyphenanthrene (1 g, 3.5 mmol) from Step 2, Example 160 in CH2Cl2 (10 mL). The reaction mixture was warmed to room temperature and stirred for 30 minutes, after which it was quenched with water. The aqueous layer was extracted with CH2Cl2. The organic layer was dried over MgSO4, filtered and concentrated to yield crude 6-bromophenanthren-3-ol.
