Reaction Steps

(3-Bromo-pyrrolo[2,3-b]pyridin-1-yl)-(2-ethoxy-naphthalen-1-yl)-methanone 85 (35 mg, 0.0088 mmol), 4-Methanesulfonyl-phenylboronic acid (35 mg, 0.18 mmol) and tetrakis(triphenylphosphine)palladium(0) (5 mg) were stirred in tetrahydrofuran (16 mL) and potassium carbonate solution (8.0 mL, 1 M aqueous). The reaction mixture was stirred over night at 60° C. The reaction mixture was concentrated under reduced pressure and partitioned between ethyl acetate and brine. The organic portion was dried over anhydrous magnesium sulfate and filtered. The filtrate was concentrated and purified by flash chromatography (ethyl acetate:hexanes 20%-100%). The desired product, 84 was obtained as a pale yellow powder (10 mg, 20%).
