Procedure

Trifluoro-methanesulfonic acid 3-cyano-6,6-dimethyl-11-oxo-6,11-dihydro-5H-benzo[b]carbazol-8-yl ester (Compound B1, 25 mg, 0.057 mmol) was dissolved in dimethoxyethane (0.5 mL), added with 2-diethylaminoethanethiol hydrochloric acid salt (19.6 mg, 2 eq.), Pd2(dba)3 (2.6 mg, 0.05 eq.), Xantphos (3.3 mg, 0.1 eq.) and DIPEA (0.06 mg, 6 eq.), and the mixture was stirred at 160° C. for 30 min. The reaction solution was added to water, extracted with ethyl acetate, and dried over magnesium sulfate. The drying agent was removed by filtration and the residues obtained after concentration under reduced pressure were purified by silica gel column chromatography (dichloromethane/methanol) to obtain the target compound (white amorphous, 22.4 mg, 93%).
