実験手順

Trifluoroacetic acid salt of 8-(2-amino-ethoxy)-6,6-dimethyl-11-oxo-6,11-dihydro-5H-benzo[b]carbazole-3-carbonitrile (Compound A8-2, 20 mg, 0.044 mmol) was dissolved in pyridine (0.5 mL), added with N-(tert-butoxycarbonyl)-N-[4-(dimethyl azaniumylidene)-1,4-dihydropyridin-1-yl sulfonyl]azanide (13.5 mg, 1 eq.), and then stirred at room temperature for 14 hr. The reaction solution was added to water, and then extracted with ethyl acetate. After washing with saturated brine, the organic layer was dried over sodium sulfate. The drying agent was removed by filtration and the residues obtained after concentration under reduced pressure were separated by silica gel preparative TLC (ethyl acetate) to obtain the title compound (16.1 mg, 68%).
