Procedure

To a solution of the compound obtained in Step 1 (300 mg, 0.95 mmol), 3-amino-9-ethylcarbazole (241 mg, 1.15 mmol) and DIEA (0.500 mL, 2.86 mmol) in DMF (6 mL) was added HATU (544 mg, 1.43 mmol), and the mixture was stirred at room temperature for 14 hr. To the reaction solution was added water, and the mixture was extracted with ethyl acetate. The organic layer was washed with water and saturated brine, and dried, and the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography (solvent gradient; 5 to 75% ethyl acetate/hexane), and then NH-silica gel column chromatography (solvent gradient; 5 to 100% ethyl acetate/hexane) to give the title compound (189 mg, 0.372 mmol, 39.0%) as a white powder.
