Procedure

A solution of N-[3-({2-({6-[(5R)-5-(2,2-dimethyl-4H-1,3-benzodioxin-6-yl)-2-oxo-1,3-oxazolidin-3-yl]hexyl}oxy)ethoxy}methyl)phenyl]-N′-(3-iodophenyl)urea (393 mg) and phenylacetylene (77 mg) in DMF (6 ml) was treated with diisopropylethylamine (5 ml) and nitrogen was passed through the solution for 5 min. Copper (I) iodide (10 mg) and dichlorobis(triphenylphosphine)palladium(II) (47 mg) were added and the mixture was stirred under nitrogen at 200 for 21.5 h. The solvent was evaporated in vacuo and EtOAc (15 ml) was added. The supernatent solution was collected and the solvent evaporated in vacuo to give a residue which was purified by Biotage. Elution with dichloromethane-ethanol-ammonia (325:8:1) gave the title compound (328 mg). LCMS RT=3.93 min, ES+ve 718 (MH)+.
