Procedure

N-(5-Phenyl-4-(piperazin-1-yl)-1H-pyrrolo[2,3-b]pyridin-3-yl)nicotinamide (0.050 g, 0.125 mmol, see Example 64), 3-(tert-butoxycarbonylamino)propanoic acid (0.0475 g, 0.251 mmol), HOBT-H2O (0.0269 g, 0.176 mmol), and EDCI (0.0313 g, 0.163 mmol) were placed in DCM (5 mL) at room temperature. DIEA (d 0.742; 0.109 mL, 0.627 mmol) was then added, and the reaction was stirred for 5 hours. The reaction was then poured into Na2CO3 and extracted into DCM. The organic fractions were dried, filtered, and concentrated to give the crude product that was purified by column chromatography (500:20 DCM:MeOH) to give tert-butyl 3-(4-(3-(nicotinamido)-5-phenyl-1H-pyrrolo[2,3-b]pyridin-4-yl)piperazin-1-yl)-3-oxopropylcarbamate (0.065 g, 90.9% yield).
