Procedure

A solution of the compound obtained in Step 2 (198 mg, 0.91 mmol), 9-ethyl-9H-carbazole-3-carboxylic acid (218 mg, 0.91 mmol), HATU (450 mg, 1.18 mmol) and TEA (0.381 mL, 2.73 mmol) in DMF (4.5 mL) was stirred at room temperature for 16 hr. Water was poured into the reaction mixture, and the mixture was extracted with ethyl acetate. The organic layer was dried, and the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography (solvent gradient; 20 to 100% ethyl acetate/hexane) to give the title compound (200 mg, 0.456 mmol, 50.0%) as a white powder.
