4-Chloro-2-phenyl-1-(2-trimethylsilanyl-ethoxymethyl)-1H-pyrrolo[2,3-b]pyridine (312 mg, 0.87 mmol) and (3-fluoro-4-hydroxy-phenyl)-carbamic acid t-butyl ester (336 mg, 1.48 mmol) were dissolved in anhydrous toluene (5 mL) under nitrogen atmosphere. After adding dicyclohexyl-phosphino-2,4,6-triisopropylbiphenyl (41 mg, 0.087 mmol), Pd2 dba3 (40 mg, 0.044 mmol) and potassium carbonate, the mixture was heated at 110° C. The resulting reaction mixture was cooled to room temperature and filtered by passing through a celite pad. The filtrate was concentrated under reduced pressure. The resulting residue was purified by silica gel chromatography (hexane: ethyl acetate=9:1) to give the target compound as a white solid (404 mg, 0.73 mmol, 84% yield).
