Using similar reaction conditions as described in step-ii of example-1, 5-bromo-3-(1-(4-fluorobenzyl)-1H-pyrazol-4-yl)-1-tosyl-1H-pyrrolo[2,3-b]pyridine (150 mg, 0.285 mmol) was coupled with N-(3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl) methane sulfonamide (intermediate 3) (127 mg, 0.427 mmol) in sodium carbonate (90.6 mg, 0.855 mmol), bis(triphenyl phosphine)palladium(ii) dichloride (39.8 mg, 0.057 mmol) and toluene/ethanol/water (20/8/2 ml) to afford 138 mg (79% yield) of the pure product after column purification using 40% ethyl acetate in hexane as eluent. MS: m/z=616.3 (M+1).
