Procedure

A solution of 5-iodo-6-methyl-N-[4-(methylsulfonyl)benzyl]-2-oxo-1-[3-(trifluoromethyl)phenyl]-1,2-dihydropyridine-3-carboxamide (Example 1 (d), 1500 mg, 2.5 mmol), bis[1,2-bis(diphenylphosphino)ethanelpalladium(0) (230 mg, 0.25 mmol), triethylamine (7.5 ml, 54 mmol) and ethylpropenyl ether (900 μl, 7.5 mmol) in DMP (45 ml) was heated at 100° C. overnight. After cooling, the reaction mixture was poured into water and extracted with ethyl acetate and the solvent was removed under reduced pressure. The crude product was then dissolved in DMP (25 ml) and 2M HCl (25 ml) and then stirred for 1.5 h. The reaction mixture was then poured into aqueous NaHCO3 and extracted with ethyl acetate. The extracts were separated, evaporated under reduced pressure, and the residue was chromatographed on silica using ethyl acetate/heptane (2/1, 4/1, 10/1) as eluent. Fractions containing the product were combined and evaporated to give the title compound (1.3 g, >99%).
