Procedure

N-({(5S)-2-Oxo-3-[4-(trimethylstannyl)phenyl]-1,3-oxazolidin-5-yl}methyl)acetamide (500 mg, 1.26 mM), [3-(5-bromothien-2-yl)-4,5-dihydroisoxazol-5-yl]methanol (330 mg, 1.26 mM), tris(dibenzylideneacetone)dipalladium (0)-chloroform adduct (130 mg, 0.126 mM) and tri-2-furylphosphine (58 mg, 0.252 mM) were placed in a flask. The solids were degassed and placed under nitrogen. Anhydrous dioxane (10 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 (220 mg).
