Procedure

5-Iodo-6-methyl-N-[4-(methylsulfonyl)benzyl]-2-oxo-1-[3-(trifluoro-methyl)phenyl]-1,2-dihydropyridine-3-carboxamide (0.10 g, 0.169 mmol), 2-tributylstannyl-oxazole (0.12 g, 0.33 mmol, prepared according to literature procedures), Pd(PPh3)4 (0.015 g, 0.012 mmol) and dimethoxyethane (DME, 2.5 ml) and a magnetic stirrer bar were placed in a vial. The suspension was degassed and the vial sealed, and subsequently heated (100° C.) with stirring for 4 h. LC-MS confirmed the conversion of the iodide to the desired product, and the solvents were removed in vacuo. Purification on preparative HPLC afforded the title compound (0.06 g, 67%) as a white solid after freeze-drying the pure fractions.
