(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 (0.05 g, 0.083 mmol, see Example 4) was placed in dioxane (1 mL) and Na2CO3 (aq., 0.087 g, 0.82 mmol) in H2O (0.3 mL). 1-Methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (0.034 g, 0.16 mmol) and PS-Pd(PPh3)4 (0.075 g, 0.1 g/mmol) were then added. The reaction was heated to 150° C. in a microwave for 1 hour. The reaction was then diluted with water and extracted with DCM. The organic fractions were dried, filtered, and concentrated. Purification of the crude residue (500:10 to 500:20 DCM:MeOH) gave (S)-tert-butyl 2-(4-chlorophenyl)-3-(4-(5-(1-methyl-1H-pyrazol-4-yl)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperazin-1-yl)-3-oxopropyl(isopropyl)carbamate (0.005 g, 9.9% yield).
