Using similar reaction conditions as described in step-ii of example-1, 5-bromo-3-(1-(3,5-difluorobenzyl)-1H-pyrazol-3-yl)-1-tosyl-1H-pyrrolo[2,3-b]pyridine (Intermediate 63) (100 mg, 0.184 mmol) was coupled with N-(2-methoxy-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)methanesulfonamide (Intermediate 17) (65 mg, 0.22 mmol) using sodium carbonate (58 mg, 0.552 mmol) and Pd(PPh3)4 (10 mg, 0.0092 mmol) in toluene/ethanol/water (2/2/1 ml) to afford 46 mg (37.7% yield) after purification by preparative TLC (silicagel-1000 micron) using 40% ethyl acetate in hexane as eluent. MS: m/z=664.1 (M+1).
