Reaction Steps

Using similar reaction conditions as described in step-i of example-1, tert-butyl 5-(5-(N-(tert-butoxycarbonyl)methylsulfonamido)-6-methoxypyridin-3-yl)-3-iodo-1H-pyrrolo[2,3-b]pyridine-1-carboxylate (intermediate 66P) (150 mg, 0.233 mmol) was coupled with 3-((4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazol-1-yl)methyl)pyridine (intermediate 64) (73 mg, 0.256 mmol) using Pd(PPh3)2Cl2 (9 mg, 0.0116 mol) and sodium carbonate (74 mg, 0.699 mmol) in toluene/ethanol/water (3/3/2 ml) to afford 60 mg (38% yield) of the titled compound after purification by column (Silica gel 60/120) using 30% ethyl acetate in hexane as eluent. MS: m/z=675.1 (M+1).
