Reaktionsbedingungen

Temperatur	95 °C

Reaktionsschritte

Compound 20b (0.264 mmol, 51 mg), CuI (0.0264 mmol, 5 mg) and K3PO4 (0.66 mmol, 40 mg) were combined in a sealed reaction tube and the vial was back-flushed with N2. 4-fluoro-iodobenzene 20c (0.264 mmol, 0.0394 mL) and N,N′-dimethylcyclohexane-1,2-diamine (0.0792 mmol, 0.0125 mL) were added via syringe, followed by toluene. The reaction mixture was heated at 95° C. for 6 h. The reaction was diluted with EtOAc and water. The reaction mixture was concentrated and purified by flash column chromatography (silica gel, 20% EtOAc/hexanes) to give compound 20d.
