Versuchsvorschrift

9-Bromo-3-chloro-8-((S)-2,2-dimethyl-[1,3]dioxolan-4-ylmethoxy)-6,6-dimethyl-5,6-dihydro-benzo[b]carbazol-11-one (Compound S7-1, 30 mg, 0.06 mmol) was dissolved in the mixture solvent of water.dioxane (1:1) (0.5 mL), added with tris(benzylidenacetone dipalladium)chloroform complex (3.1 mg, 0.05 eq.), 2-di-tert-butylphosphino-2′,4′,6′-triisopropylbiphenyl (2.5 mg, 0.1 eq.) and KOH (0.5 N aqueous solution 180 μL, 1.5 eq.), and stirred at 60° C. for 12 hr. After cooling, the reaction solution was concentrated under reduced pressure, and the resulting residues were purified by HPLC to obtain the title compound (white solid, 4.6 mg).
