실험 절차

A solution of N-cyclohexyl-3-(hydroxymethyl)-N-({2-(trimethylsilyl)ethoxy}-methyl)benzenesulfonamide (508 mg) in DMF (8 ml) under nitrogen at 20° was treated with sodium hydride (60% dispersion in mineral oil, 58 mg) and the mixture was stirred 15 min. A solution of 2-({6-[(5R)-5-(2,2-dimethyl-4H-1,3-benzodioxin-6-yl)-2-oxo-1,3-oxazolidin-3-yl]hexyl}oxy)ethyl methanesulfonate (400 mg) in DMF (2 ml) was added and the mixture was stirred at 20° for 72 h. Phosphate buffer solution (pH 6.5, 10 ml) and water (20 ml) were added and the mixture was extracted with EtOAc (30 ml). The extract was washed with water (2×30 ml), dried (Na2SO4) and the solvent evaporated in vacuo. The residue was purified by flash chromatography on silica gel. Elution with EtOAc-PE (1:1) gave the title compound (530 mg). LCMS RT=4.47 min, ES+ve 793 (MH)+.
