Reaction Steps

To 2-[3-(5 Bromo-1H-pyrrolo[2,3-b]pyridin-3-ylmethyl)-2,4-difluoro-phenoxy]-ethanol (P-1392, 35.0 mg, 0.091 mmol) in acetonitrile (4.0 mL) were added 3-pyridylboronic acid (14.6 mg, 0.12 mmol), tetrakis(triphenylphosphine)palladium(0) (3.0 mg, 0.0026 mmol) and 1 M potassium carbonate solution (1.5 mL). The reaction was microwaved (300 watts) at 160° C. for 7 minutes. The reaction was poured into water and extracted with ethyl acetate. The organic layer was collected and dried over anhydrous sodium sulfate and filtered. The filtrate was concentrated and purified by silica gel column chromatography eluting 4% methanol in methylene chloride to give the compound as white solid (P-1394, 11.0 mg, 32%). MS (ESI) [M+H+]+=382.2.
