Reaction Steps

Using similar reaction conditions as described in step-ii of example-1, tert-butyl 5-(4-(4-(tert-butoxycarbonyl)piperazin-1-yl)-3-(methylsulfonamido)phenyl)-3-iodo-1H-pyrrolo[2,3-b]pyridine-1-carboxylate (intermediate 50) (200 mg, 0.286 mmol) was coupled with 1-(3-fluorobenzyl)-3,5-dimethyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (intermediate 16) (123 mg, 0.373 mmol) in sodium carbonate (90 mg, 0.858 mmol), Pd(PPh3)2Cl2 (10 mg, 0.0143 mmol), Toluene/ethanol/water (5/5/2.5 ml) to afford 6 mg (2.7% yield) of titled compound. MS: m/z=774.2 (M+1).
