Procedure

A mixture of 5-(2-chlorophenyl)-2-iodo-1,3-oxazole-4-carboxamide (0.051 g, 0.14 mmol), N-[5-methyl-4-(trimethylstannyl)pyridine-2-yl]cyclopropanecarboxamide (0.064 g, 0.19 mmol), tetrakis(triphenylphosphine)palladium(0) (0.008 g, 0.007 mmol), copper(I) iodide (0.008 g, 0.043 mmol), and lithium chloride (0.018 g, 0.43 mmol) in 1,4-dioxane (1.5 mL) was degassed with argon three times and then allowed to stir at 100° C. under an atmosphere of argon for 5 h. The reaction mixture was filtered while hot and the filtrate was concentrated. The residue was purified by column chromatography to give 5-(2-chlorophenyl)-2-{2-[(cyclopropylcarbonyl)amino]-5-methylpyridin-4-yl}-1,3-oxazole-4-carboxamide (Compound I-86) (0.036 g, 62%). LCMS (AA): m/z=397 (M+H).
