実験手順

3-Bromo-9-((S)-2,2-dimethyl-[1,3]dioxolan-4-yl methoxy)-6,6-dimethyl-5,6-dihydro-benzo[b]carbazol-11-one (Compound JJ3-1, 18.7 mg, 0.0398 mmol) was dissolved in methanol (1 mL) and THF (0.3 mL), added with 1 N hydrochloric acid (5 drops) and stirred at 50° C. for 1 hr. After cooling, the reaction solution was concentrated under reduced pressure, and the resulting residues were added with dichloromethane, and the solid was separated by filtration to obtain the title compound (yellow powder, 16.8 mg, 98%).
