Procedure

N-{[(5S)-3-(3-Fluoro-4-iodophenyl)-2-oxo-1,3-oxazolidin-5-yl]methyl}acetamide (273 mg, 0.72 mM), {3-[5-(trimethylstannyl)thien-2-yl]-4,5-dihydroisoxazol-5-yl}methanol (250 mg, 0.72 mM), tris(dibenzylideneacetone)dipalladium (0)-chloroform adduct (75 mg, 0.072 mM) and tri-2-furylphosphine (34 mg, 0.145 mM) were placed in a flask. The solids were degassed and placed under nitrogen. Anhydrous dioxane (5 ml) was added and the suspension was heated at 90° C. for 16 hours. The reaction mixture was cooled and the solvent was evaporated. The residue was chromatographed on silica gel eluting with 5% methanol in dichloromethane to give the title compound (180 mg).
