Reaction Steps

Pyridin-3-ylboronic acid (20 mg, 0.17 mmol), PS-tetrakis (41 mg, 0.0041 mmol) and sodium carbonate (18 mg, 0.17 mmol, 2N aqueous solution) were added to (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 (50 mg, 0.083 mmol, see Example 4) in degassed (Ar) dioxane (1 mL). The reaction was heated to 160° C. for 1 hour under microwave irradiation. After cooling down, the reaction was diluted with DCM, filtered, dried over MgSO4 and concentrated to dryness. The resulting residue was purified by reverse phase column chromatography (water:ACN 4:1 to 1:9) to yield (S)-tert-butyl 2-(4-chlorophenyl)-3-oxo-3-(4-(5-(pyridin-3-yl)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperazin-1-yl)propyl(isopropyl)carbamate (32 mg, 64% yield) as a solid.
