Reaction Steps

To a degassed solution of (1-(tert-butoxycarbonyl)-5-methoxy-1H-pyrrolo[3,2-b]pyridin-2-yl)boronic acid (500 mg, 1.17 mmol), NaHCO3 (287 mg, 3.42 mmol) and 6-chloro-2-iodopyridin-3-ol (525 mg, 2.05 mmol) in 1,4-dioxane (10 mL) was added Pd(dppf)Cl2 (10 mg) under N2. The mixture was heated at 70° C. for 5 hours, concentrated in vacuo to remove 1,4-dioxane and extracted with EtOAc. After washed with brine and dried over Na2SO4, the solvent was removed by distillation. After concentrated, the crude product of tert-butyl 2-(6-chloro-3-hydroxypyridin-2-yl)-5-methoxy-1H-pyrrolo[3,2-b]pyridine-1-carboxylate (260 mg, yield: 40%). MS (M+H)+: 376/378.
