Procedure

To a stirring solution of N-(5-chloropyridin-2-yl)-5-iodo-2-[(1-isopropylpiperidin-4-ylcarbonyl)amino]benzamide (0.29 g, 0.54 mmol), tetrakis (triphenylphosphine)-palladium(0) (35 mg, 0.03 mmol), and phenylboronic acid (81 mg, 0.66 mmol) in toluene (5 mL) was added water (0.55 mL) and a 2 M aqueous sodium carbonate solution (0.55 mL, 1.1 mmol). The mixture was heated to 85-95° C. for 1 h, cooled to room temperature, partitioned between ethyl acetate and saturated aqueous sodium bicarbonate. The organic phase was treated with 0.002 N aqueous hydrochloric acid. To the aqueous phase was added dichloromethane followed by saturated aqueous sodium bicarbonate until pH 8-9. The phases were separated and the organic phase was concentrated. The crude product was purified by RPHPLC, eluting with a gradient from 25% through 65% acetonitrile in 0.05% aqueous hydrochloric acid, to give 0.16 g (57%) of a yellow solid.
