1-Ethyl-3-(3'-dimethylaminopropyl)carbodiimide → HCID 131731885, Verbindung

5-(3-Methoxyphenyl)-4-(piperazin-1-yl)-1H-pyrrolo[2,3-b]pyri dine (0.045 g, 0.118 mmol, see Example 8) and (S)-3-(tert-butoxycarbonyl(isopropyl)amino)-2-(4-chlorophenyl)propanoic acid (0.0424 g, 0.124 mmol, see Example H) were placed in DCM (3 mL). HOBT-H2O (0.0253 g, 0.165 mmol), EDCI (0.0294 g, 0.153 mmol), and DIEA (d 0.742; 0.103 mL, 0.590 mmol) were then added, and the reaction was stirred at room temperature for 2 hours. The reaction was then quenched with saturated Na2CO3 and extracted with DCM. The product was dried, filtered, and concentrated to give the crude product. The crude product was purified (500:5 DCM:MeOH) to yield (S)-tert-butyl 2-(4-chlorophenyl)-3-(4-(5-(3-methoxyphenyl)-1H-pyrrolo[2, 3-1)]pyridin-4-yl)piperazin-1-yl)-3-oxopropyl(isopropyl)carbamate (0.040 g, 53.6% yield).
