4-Acetylamino-3-chloro-6-(4-chloro-2-fluoro-3-methoxyphenyl)-pyridine-2-carboxylic acid methyl ester (500 mg, 1.29 mmol), tetramethyltin (924 mg, 5.17 mmol), bis(triphenylphosphine)palladium(II) dichloride (91 mg, 0.129 mmol), and tetrabutylammonium triphenyldifluorosilicate (1.395 g, 2.58 mmol) were combined in 2 mL of acetonitrile and heated in a CEM microwave reactor at 110° C. for 15 min. The resulting reaction mixture was filtered and concentrated. This intermediate product was purified by flash chromatography on silica gel (ethyl acetate/hexane gradient) to yield the title compound (419 mg, 88% yield). mp 182-184° C.
