Using similar reaction conditions as described in step-ii of example-1, 5-bromo-3-(1-(3-fluorobenzyl)-1H-pyrazol-4-yl)-1-tosyl-1H-pyrrolo[2,3-b]pyridine (compound of Step-i of example 9) (150 mg, 0.286 mmol) was coupled with tert-butyl 4-(5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-2-yl)piperazine-1-carboxylate (intermediate 69C) (167 mg, 0.429 mmol) in sodium carbonate (76 mg, 0.715 mmol), Pd(PPh3)2Cl2 (10 mg, 0.014 mmol), DME/water (5/1 mL). This afforded 140 mg (69.0% yield) after purification by column chromatography (60-120 silica gel) using 2% methanol in DCM as eluent. MS: m/z=708.3 (M+1).
