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) (150 mg, 0.215 mmol) was coupled with 1-(3-fluorobenzyl)-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (intermediate 11) (78 mg, 0.258 mmol) using sodium carbonate (68 mg, 0.645 mmol) and Pd(PPh3)2Cl2 (8 mg, 0.0107 mmol) in toluene/ethanol/water (5/2.5/1 ml) to afford 30 mg (18.7% yield) of titled compound after purification by preparative TLC (Silicagel-1000 micron) using 1% methanol in DCM as eluent.
