実験手順

3-Chloro-4-fluoro-8-methoxy-6,6-dimethyl-5,6-dihydro-benzo[b]carbazol-11-one (Compound S1-3, 220.0 mg, 0.640 mmol) and pyridinium chloride (800 mg, 6.922 mmol) were mixed with each other, heated to 160° C., and then stirred for 20 hr. The reaction solution was added with water. As a result, black solid was obtained as a precipitate, which was then filtered and subjected to purification by silica gel column chromatography (ethyl acetate/hexane) to obtain the title compound (139.4 mg, 66%).
