Reaction Steps
To a solution of 9-ethyl-9H-carbazol-3-ylamine (306.5 mg, 1.457 mmol) in DMF (7 mL) were added the compound obtained in Step 1 (300 mg, 1.215 mmol), HATU (554.14 mg, 1.457 mmol) and DIPEA (0.632 mL, 3.644 mmol) at room temperature, and the mixture was stirred at room temperature for 16 hr. To the reaction mixture was added water, and the mixture was extracted with ethyl acetate (2×50 mL). The organic layer was dried, and the solvent was evaporated under reduced pressure. The obtained residue was purified by preparative HPLC to give the title compound (260 mg, 48.71%) as a colorless powder.
