Procedure

N-({(5S)-2-Oxo-3-[4-(trimethylstannyl)phenyl]-1,3-oxazolidin-5-yl}methyl)acetamide (300 mg, 0.76 mM), [3-(5-bromopyridin-2-yl)-4,5-dihydroisoxazol-5-yl]methanol (194 mg, 0.76 mM), tris(dibenzylideneacetone)dipalladium (0)-chloroform adduct (78 mg, 0.076 mM) and tri-2-furylphosphine (35 mg, 0.152 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 15 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 (83 mg).
