1-Ethyl-3-(3'-dimethylaminopropyl)carbodiimide → (R)-tert-butyl 3-(4-chlorophenyl)-1-(4-(5-(3-fluorophenyl)-1H-pyrrolo [2,3-b]pyridin-4-yl)piperazin-1-yl)-1-oxopropan-2-ylcarbamate

5-(3-Fluorophenyl)-4-(piperazin-1-yl)-1H-pyrrolo[2,3-b]pyri dine (0.062 g, 0.168 mmol) and (R)-2-(tert-butoxycarbonylamino)-3-(4-chlorophenyl)propanoic acid (0.0604 g, 0.201 mmol) were placed in DCM (3 mL) at room temperature. HOBT-H2O (0.0360 g, 0.235 mmol), EDCI (0.0418 g, 0.218 mmol), and DIEA (d 0.742; 0.146 mL, 0.840 mmol) were then added. The reaction was stirred at room temperature for 2 hours. The reaction was then quenched with saturated Na2CO3 and extracted with DCM. The organic fractions were dried, filtered, and concentrated to give a crude oil. The oil was purified by column chromatography (500:5 D CM: MeOH) to give (R)-tert-butyl 3-(4-chlorophenyl)-1-(4-(5-(3-fluorophenyl)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperazin-1-yl)-1-oxopropan-2-ylcarbamate (0.045 g, 46.3% yield).
