Procedure

A solution of 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}-N,N-bis{[2-(trimethylsilyl)ethoxy]methyl}benzenesulfonamide (200 mg) in THF (10 ml) under nitrogen was treated with potassium trimethylsilanolate (125 mg) and the mixture heated to 70° for 5 h. The mixture was cooled to 20° and phosphate buffer solution (25 ml, pH6.5) was added. The mixture was extracted with EtOAc, the extract dried (Na2SO4) and the solvent evaporated in vacuo to give the title compound (400 mg). LCMS RT=3.6 min.
