Vorschrift

5-Bromo-4-(piperazin-1-yl)-1H-pyrrolo[2,3-b]pyridine dihydrochloride (0.100 g, 0.282 mmol, see Example 1), (S)-3-(tert-butoxycarbonyl(isopropyl)amino)-2-(4-chlorophenyl)propanoic acid (0.145 g, 0.424 mmol, see Example H), HOBT-H2O (0.0606 g, 0.395 mmol), EDCI (0.0704 g, 0.367 mmol), and triethylamine (0.0394 mL, 0.282 mmol) were stirred in DCM (5 mL) at room temperature for 5 hours. The reaction was then quenched with saturated Na2CO3 and extracted into DCM. The organics were dried, filtered, and concentrated to give the crude product. Purification (500:6 DCM:MeOH) gave (S)-tert-butyl 3-(4-(5-bromo-1H-pyrrolo[2,3-b]pyridin-4-yl)piperazin-1-yl)-2-(4-chlorophenyl)-3-oxopropyl(isopropyl)carbamate (0.103 g, 60.2% yield).
