実験手順

Mixture of 2,3-dichloro-8-methoxy-6,6-dimethyl-5,6-dihydro-benzo[b]carbazol-11-one (Compound Y3, 16.5 mg, 0.0457 mmol) and pyridinium chloride (0.2 g) was stirred at ambient temperature of 160° C. for 7 hr. The reaction mixture was cooled to room temperature and added with ethyl acetate and water. The mixture was extracted three times with ethyl acetate. The organic layer was washed twice with water, dried over sodium sulfate, and concentrated under reduced pressure. The resulting crude product was used for the next step without further purification (brown solid, 14.8 mg, 94%).
