Procedure
To the tetrahydrofuran (1 ml) solution of 3-cyano-6,6-dimethyl-11-oxo-6,11-dihydro-5H-benzo[b]carbazol-8-carboxylic acid (Compound B2-28, 15 mg, 0.045 mmol), morpholine (6 μl, 1.5 eq.), hexafluorophosphoric acid uronium 2-(1H-7-azabenzotriazol-1-yl)-1,1,3,3-tetramethylmethane aminium (HATU) (26 mg, 1.5 eq.), and N,N-diisopropylethylamine (24 μl, 3.0 eq.) were added and the mixture was stirred at room temperature for 3 hr. The reaction solution was filtered to remove insoluble matters and the residues obtained after concentration under reduced pressure were purified by high performance liquid chromatography to obtain the title compound (11 mg, 55%).
