実験手順

(R)-tert-Butyl 1-(4-(5-bromo-1H-pyrrolo[2,3-b]pyridin-4-yl)piperazin-1-yl)-3-(4-chlorophenyl)-1-oxopropan-2-ylcarbamate (0.180 g, 0.320 mmol, see Example 1), phenylboronic acid (0.0468 g, 0.384 mmol), Pd(PPh3)4 (0.0185 g, 0.0160 mmol) and 10% K2CO3 (aq., 0.66 mL, 0.47 mmol) were added to an Ar degassed solution of 2:1 toluene:EtOH (3 mL). The reaction was then heated to 80° C. overnight. The reaction was then cooled to room temperature, diluted with water, and extracted with DCM. The organic fractions were dried, filtered, concentrated, and purified (500:10-500:15) to give (R)-tert-butyl 3-(4-chlorophenyl)-1-oxo-1-(4-(5-phenyl-1H-pyrrolo[2,3-b]pyridin-4-yl)piperazin-1-yl)propan-2-ylcarbamate (0.018 g, 10.0% yield).
