実験手順

4H-cyclopenta[def]phenanthrene (4.75 g, 25 mmol) was placed in a Par reactor bottle, and EtOH (200 ml) was added thereto. 5% Pd/C (3.99 g) was added to the reaction solution, and the resultant solution was incubated under a hydrogen pressure of 40 psi for 24 hours. After the reaction was terminated, the reaction solution was filtered, and the filtrate was concentrated under a reduced pressure to give a white product (4.42 g, 90%).
