Procedure

To a solution of 12.5 g (58.7 mmol) of 3-chlorophenanthrene from Step 3 in 350 mL of acetic acid was added 23.5 g (0.23 mol) of CrO3. The reaction was stirred 2 hrs at 100° C., cooled down to room temperature and poured into 2 L of water. The suspension was stirred 1 hr, filtered and washed with water. The residue was dried under high vacuum to afford 12.5 g (88%) of 3-chlorophenanthrene-9,10-dione.
