Versuchsvorschrift

5-Iodo-6-methyl-N-[4-(methylsulfonyl)benzyl]-2-oxo-1-[3-(trifluoromethyl)phenyl]-1,2-dihydropyridine-3-carboxamide (Example 1 (d), 101.5 mg, 0.17 mmol), bis[1,2-bis(diphenylphosphino)ethane]-palladium (0) (16.5 mg, 18.3 μmol), n-butyl vinyl ether (60 μl, 0.46 mmol), triethylamine (0.5 ml, 3.6 mmol) and DMF (6 ml) were placed in a Schlenk vessel equipped with a magnetic stirring bar. The vessel was purged with argon, sealed, and heated at 100° C. overnight. The reaction mixture was cooled and partitioned between ethyl acetate and water. The organic layer was dried over sodium sulphate, filtered and concentrated in vacuo. The residue was purified by preparative HPLC to give the title compound as a white solid (27.3 mg, 28%).
