With the same synthesis condition as the Compound A7-17 (8-hydroxy-6,6-dimethyl-11-oxo-6,11-dihydro-5H-benzo[b]carbazole-3-carbonitrile (Compound A6, 25 mg, 0.083 mmol) was dissolved in N,N-dimethylacetamide (1 mL), added with 2-chloroethyldiethylamine (16 mg, 1.1 eq.) and cesium carbonate (54 mg, 2 eq.) in order and stirred at 100° C. for 4 hours. The reaction solution was poured into water and extracted with ethyl acetate. The organic layer was washed with brine and dried over sodium sulfate. The drying agent was removed by filtration and the residues obtained after concentration under reduced pressure were purified by amino silica gel column chromatography (ethyl acetate/hexane) to obtain the Compound A7-17 (8-(2-diethylamino-ethoxy)-6,6-dimethyl-11-oxo-6,11-dihydro-5H-benzo[b]carbazole-3-carbonitrile) (11 mg, 32%)), the title compound was synthesized from the Compound A7-24 and tert-butyl amine.
