Using similar reaction conditions as described in step-ii of example-1, 5-bromo-3-(1-(2,5-difluorobenzyl)-1H-pyrazol-4-yl)-1-tosyl-1H-pyrrolo[2,3-b]pyridine (step-i of example-4) (200 mg, 0.368 mmol) was coupled with N-(2-methoxy-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)methanesulfonamide (Intermediate 17) (120 mg, 0.368 mmol) using sodium carbonate (117 mg, 1.1049 mmol) and Pd(PPh3)2Cl2 (14 mg, 0.018 mmol) in DME/water (15/2 ml) to afford 121 mg (49.5% yield) after purification by column chromatography (Silica gel 230/400) using 50% ethyl acetate in hexane as eluent. MS: m/z=664.2 (M+1).
