実験手順

To a solution of 3-bromo-6-chlorophenanthrene from Step 2 (1.71 g; 5.86 mmol) in 35 mL of acetic acid was added 2.3 g (23.5 mmol) of CrO3. The mixture was stirred 2 hrs at 100° C., cooled down to room temperature, poured into 300 mL of water and stirred for 1 hr. The suspension was filtered, washed with water and Et2O and pumped under reduced pressure to afford 1.67 g of 3-bromo-6-chlorophenanthrene-9,10-dione as a solid.
