3-Amino-9-ethylcarbazole → HCID 86729728, compound

Participants

Reaction Steps

To a solution of the compound obtained in Step 1 (200 mg, 0.97 mmol), 9-ethyl-9H-carbazol-3-amine (217 mg, 1.03 mmol) and DIEA (0.451 mL, 2.58 mmol) in DMF (6 mL) was added HATU (491 mg, 1.29 mmol), and the mixture was stirred at room temperature for 14 hr. The reaction mixture was poured into water, and 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) to give the title compound (229 mg, 0.540 mmol, 62.7%) as a white powder.
