Procedure

5-Iodo-6-methyl-N-[4-(methylsulfonyl)benzyl]-2-oxo-1-[3-(trifluoromethyl)phenyl]-1,2-dihydropyridine-3-carboxamide (25 mg, 0.042 mmol), tetrakis(triphenylphosphine)palladium (2.5 mg, 0.0022 mmol) and 3-methyl-4-(tributylstannyl)isoxazole [synthesized as described by D. Uchiyama in Heterocycles, 43, 6, 1301, 1996] (32 mg, 0.086 mmol) were mixed in DME (0.45 ml) in an argon filled vial. The vial was closed and heated with stirring at 100° C. for 24 h. The reaction mixture was poured into a mixture of ethyl acetate and water. The mixture was shaken, the water phase was removed and the organic phase was dried over sodium sulphate. The product was purified by preparative HPLC. Yield: 12 mg, 0.022 mmol (52%).
