3-Chloro-9-bromo-8-((S)-2,2-dimethyl-[1,3]dioxolan-4-ylmethoxy)-6,6-dimethyl-5,6-dihydro-benzo[b]carbazol-11-one (Compound S7-1, 56 mg, 0.11 mmol) was dissolved in methanol (5 mL), added with 1 N hydrochloric acid (0.2 ml), and stirred at 50° C. for 2 hr. After cooling, the reaction solution was concentrated under reduced pressure and the resulting residues were added with methanol to obtain a precipitated solid, which was then filtered to obtain the title compound (white powder, 26 mg).
